autosupport.enable
Enables/disables the autosupport email notification
feature (see na_autosupport(8)). The
default is on to cause autosupport mail to be
sent.
autosupport.mailhost
Defines the list of up to 5 mailhost names.
The host names should be entered as a commaseparated
list with no spaces in between.
The default is an empty list.
autosupport.to Defines the list of recipients for the autosupport email notification. Up to 5 mail addresses are allowed. Enter the addresses as a comma-separated list with no spaces in between. The default is autosupport@netapp.com.
autosupport.noteto
Defines the list of recipients for the autosupport
short note email. Up to 5 mail
addresses are allowed. Enter the addresses as
a comma-separated list with no spaces in
between. The default is a null list to disable
short note emails.
autosupport.from
Defines the user to be designated as the sender of the notification. The default is autosupport.
autosupport.doit
Triggers the autosupport daemon to send email
notification immediately. A text word entered
as the option is sent in the notification
subject line and should be used to explain
the reason for the notification.
cifs.access_logging_enable
When on, enables the filer to process access
logging, or auditing, information. The
default is off.
cifs.access_logging.filename
Specifies the active event log file. The
file must be in an existing directory in a
network share.
cifs.bypass_traverse_checking
When on (the default), directories in the
path to a file are not required to have the
`X' (traverse) permission. This option does
not apply in UNIX qtrees.
cifs.guest_account
Enables a user to get access to the filer
provided that either the filer uses a Domain
Controller for authentication and the user is
not in a trusted domain, or the filer uses
the /etc/passwd file or the NIS password
database for authentication and the user has
no entry in the /etc/passwd or the NIS password
database. If this option is set to the
name of an account in the password database,
a user logging into the filer will be
assigned to the guest account if their name
is not listed in the password database (when
using /etc/passwd or NIS) or if the user is
not from a trusted domain (when using a
domain controller). The configured user name
will be used for the UNIX user ID, group ID,
and group set of the specified account. If
the option is blank, guest access is disabled.
cifs.home_dir When set to the pathname of a directory, this defines the path to the ``homes directory''. The directories under this path should have the names of users as their names. When a user connects to the filer using CIFS and there is a directory name that exactly matches the user's lower-cased Windows login name, they will see a share of that name (truncated to 12 characters) that is their ``home directory". Only the user can access the home directory using this share. All other users cannot see the share name since they are logged in under a different user.
cifs.idle_timeout
Specifies the amount of idle time in seconds
before the filer disconnects a session. An
idle session is a session in which a user
does not have any files opened on the filer.
The value of this option ranges from 600 to
4,000,000 (effectively infinite). The
default is 1800.
cifs.netbios_aliases
Provides a comma-separated list of alternative
names for the filer. A user can connect
to the filer using any of the listed names.
cifs.oplocks.enable
When cifs.oplocks.enable is on (the default),
the filer allows clients to use oplocks
(opportunistic locks) on files. Oplocks are
a significant performance enhancement, but
have the potential to cause lost cached data
on some networks with impaired reliability or
latency, particularly wide-area networks. In
general, this option should be disabled only
to isolate problems.
cifs.perm_check_use_gid
This option affects security checking for
Windows clients of files with UNIX security
where the requestor is not the file owner. In
all cases Windows client requests are checked
against the share-level ACL, then if the
requestor is owner, the "user" perms are used
to determine the access.
If the requestor is not owner and if perm_check_use_gid is "on" it means files with UNIX security are checked using normal UNIX rules, i.e. if the requestor is a member of the file's owning group the "group" perms are used, otherwise the "other" perms are used.
If the requestor is not owner and if perm_check_use_gid is "off", files with UNIX security style are checked in a way which works better when controlling access via share-level ACLs. In that case the requestor's desired access is checked against the file's "group" permissions, and the "other" permissions are ignored. In effect, the "group" perms are used as if the Windows client were always a member of the file's owning group, and the "other" perms are never used.
The default setting is "on" for new installations. For existing installations, this has the opposite effect of the old "PC-mode" installation setting.
If you do not plan to use share-level ACLs to control access to UNIX security style files (e.g. in a UNIX qtree), you might wish to change this setting to "on."
cifs.save_case By default, the filer preserves the case of CIFS names, even though a case insensitive hash and search is done. Setting this option to OFF forces names to be saved in lower case, avoiding some of the case conversion problems with non-ASCII characters and preventing PC applications from changing the names of files that were created with lower case names from UNIX.
cifs.scopeid NetBIOS scope IDs allow the system administrator to create small workgroups out of a network by partitioning the NetBIOS name space; only clients with the same NetBIOS scope ID as the filer will be able to use the filer as a CIFS server. Normally, the scope ID is a null string, but if the filer is to run in a NetBIOS scope other than the default one, its scope ID must be set to the scope ID of that scope. The scope ID can be changed only when CIFS is not running.
cifs.search_domains
Specifies a list of domains that trust each
other to search for a mapped account. The
argument for the option is a comma-separated
list that is searched in order. If no list
is supplied, all domains are searched. You
use this option to control searches if you
used an asterisk for a domain name in the
usermap.cfg file.
cifs.show_snapshot
By default this option is FALSE. The snapshot
directory ~snapshot is no longer shown at the
root of a share. This is a change in
behavior from previous versions. Setting
this to TRUE will restore the old behavior.
On Windows NT 4 or Windows 95 clients, the
user can access snapshots by entering
\\filer\share\.snapshot (or ~snapshot or
~snapsht) in the Start->Run menu. Snapshots
can also be accessed lower in the share by
providing a path to a lower directory.
Snapshots can be accessed through DOS on any
system by changing to the ~snapsht directory.
NOTE: When this option is TRUE it can confuse programs like FastFind that don't know about snapshots.
cifs.symlinks.cycleguard
The cifs.symlinks.cycleguard option (on by
default), eliminates the possibility of
traversing directories cyclically during the
process of following symbolic links. With
this option set to on, if the target of the
symlink resolves to a directory that is
directly above the symlink's parent directory,
it is disallowed.
With this option set to off, many standard Windows apps (such as Find in Win95 / NT4.0) will not operate correctly when a symlink points to a parent directory. This is because they do not understand symbolic links and will repeatedly loop on them. Users should use caution when changing this option.
cifs.symlinks.enable
When cifs.symlinks.enable is on (the
default), if the object being accessed by a
CIFS client is a symbolic link (whether absolute
or relative), the filer follows the link
with the proviso that the ultimate target
turns out to reside within the originating
share (thus ensuring that the client has
access permission to the target).
cifs.trace_login
When cifs.trace_login is on (the default is
off), the filer logs all login-related
activities. This can be used to diagnose
access problems on the filer.
console.encoding
Specifies how non-ASCII character information
is presented. The value can be:
nfs - NFS character set. You can use both NFS extended (> 0x7F) and SGML characters for input.
sgml - SGML character format. You can use both NFS extended (greater than 0x7F) and SGML characters for input.
utf8 - UTF-8 character sets. For input, any character greater than 0x7F is the beginning of a UTF-8 encoding.
The default is nfs.
dns.domainname Sets the DNS domainname to the specified domainname.
httpd.log.max_file_size
Specifies the maximum size that the HTTP log
file /etc/log/httpd.log can grow to. The
default is 2147483647, which is the largest
file size that many clients support.
httpd.rootdir Specifies the complete pathname of the root directory that contains files and subdirectories for HTTP access.
httpd.timeout Specifies the minimum amount of time (in seconds) before an idle HTTP 15 connection will time out. The default is 900 seconds, which is fifteen minutes.
httpd.timewait.enable
When enabled, the filer will put HTTP connections
that have been closed by the client
into the TIME_WAIT state for one minute,
which is twice the maximum segment lifetime
(2*MSL). By default, TIME_WAIT state is
bypassed for HTTP connections.
ip.match_any_ifaddr
If the option is on, the filer will accept
any packet that is addressed to it even if
that packet came in on the wrong interface.
If you are concerned about security, you
should turn this off.
nfs.mount_rootonly
When enabled, the mount server will deny the
request if the client is not root user using
privileged ports. By default, the feature is
enabled for more secure access.
nfs.per_client_stats.enable
Enables/disables the collection and display
of per-client NFS statistics, as described in
na_nfsstat(1).
nfs.tcp.enable When enabled, the NFS server supports NFS over TCP. By default, the feature is enabled; it can be disabled if there is a problem with some client when using NFS over TCP, and that client cannot be configured to use NFS over UDP.
nfs.v2.df_2gb_lim
Causes the filer to return replies to the
"file system statistics" NFS version 2
request that show no more than (2**31)-1 (or
2,147,483,647) total, free, or available
bytes (i.e., 2GB) on the file system.
Some NFS clients require this option because, if they get return values from the "file system statistics" request with more than the specified number of bytes, they'll incorrectly compute the amount of free space on the file system, and may think that there's no free space on a file system that has more than 2GB free.
nfs.v3.enable When enabled, the NFS server supports NFS version 3. By default, the feature is enabled; it can be disabled if there is a problem with some client when using NFS version 3, and that client cannot be configured to use NFS version 2.
nfs.webnfs.enable
When enabled, the NFS server supports WebNFS
lookups. By default, WebNFS lookups are disabled.
nfs.webnfs.rootdir
Specifies the WebNFS rootdir. Once the rootdir
is set, WebNFS clients can issue lookups
relative to the rootdir using the public
filehandle.
nfs.webnfs.rootdir.set
After specifying the rootdir, this option
needs to be enabled for the rootdir setting
to take effect. Disabling this option disables
the existing rootdir setting.
nis.domainname Sets the NIS domain to the specified domainname.
raid.reconstruct_speed
Specifies the speed at which the RAID reconstruction
should occur ranging from the
slowest speed 1 to the fastest speed possible
10. The RAID reconstruction process is given
more cpu time as the speed is increased, so
increasing the speed of the reconstruction
will take away cpu time for network operations.
The default speed is 4, which is
roughly 40% of the cpu time, though more time
may be used if there is idle time available.
raid.scrub.enable
Enables/disables the RAID scrub feature (see
na_disk(1)). By default, it is enabled. This
option only affects the scrubbing process
that gets started from cron. For user
requested scrubs, this option is ignored.
telnet.hosts Specifies up to 5 clients that will be allowed telnet access to the server. The host names should be entered as a commaseparated list with no spaces in between. Enter a "*" to allow access to all clients; this is the default. Enter a "-" to disable telnet access to the server.
To avoid overburdening the time server, the filer randomly selects the exact time of the synchronization within a 20-minute window.
timed.servers Specifies up to five time servers used by the time daemon. Time servers are contacted in the order specified; if a server can't be contacted, the time daemon tries the next one in the list.
wafl.convert_ucode
Setting this option to ON forces conversion
of all directories to Unicode format when
accessed from both NFS and CIFS. By default
(OFF), access from CIFS causes conversion of
pre-4.0 and 4.0 format directories; access
from NFS causes conversion of 4.0 format
directories.
vol.copy.throttle
Specifies the default speed of all volume
copy operations. The speed can be a number
in the range from 1 to 10, 10 being the
highest speed and the default.
wafl.create_ucode
Setting this option to ON forces Unicode format
directories to be created by default,
both from NFS and CIFS. By default(OFF), all
directories are created in pre-4.0 format and
the first CIFS access will convert it to
Unicode format.
wafl.default_nt_user
Specifies the NT user account to use when a
UNIX user accesses a file with NT security
(has an ACL), and that UNIX user would not
otherwise be mapped. If this option is set
blank, such accesses will be denied.
wafl.default_unix_user
Specifies the UNIX user account to use when
an NT user attempts to log in and that NT
user would not otherwise be mapped. If this
option is set blank, such accesses will be
denied.
wafl.maxdirsize
Sets the maximum size (in K-Bytes) that a
directory can grow to. This is set to 10240
by default; it limits directory size to 10MBytes
and can hold over 300,000 files. Most
users should not need to change this setting.
This option is useful for environments where
system users may grow a directory to a size
that starts impacting system performance.
When a user tries to create a file in a
directory that is at the limit, the system
returns a ENOSPC error and fails the create.
wafl.nt_admin_priv_map_to_root
When on (the default), an NT administrator is
mapped to UNIX root.
wafl.root_only_chown
When enabled, only the root user can change
the owner of a file. When disabled, non-root
users can change the owner of files that they
own. When a non-root user changes the owner
of a file they own, both the set-UID and
set-GID bits of that file are cleared for
security reasons. A non-root user is not
allowed to give away a file if it would make
the recipient overrun its user quota.
wafl.root_only_chown is enabled by default.
wafl.wcc_minutes_valid
Specifies the number of minutes a WAFL
credential cache entry is valid. The value
can can range from 1 through 20160. The
default is 20.
Multiple options can be set at once in an options command. For example:
options nfs.tcp.enable on nfs.v2.df_2gb_lim on raid.timeout 48
However, a few options must have the same setting for both filers in a cluster for takeover to work properly. If you change the setting for one of these options on one filer, the filer displays a message reminding you to make the same change on the other filer. In takeover mode, the same option values are used for both filers.
The following list of options must have the same value on both filers in a cluster:
dns.domainname dns.enable httpd.admin.enable Data ONTAP 5.3 Last change: 20 September 1998 12 User Commands na_options(1) httpd.enable httpd.timeout httpd.timewait.enable image.throttle ip.path_mtu_discovery.enable nfs.per_client_stats.enable nfs.tcp.enable nfs.v2.df_2gb_lim nfs.v3.enable nis.domainname nis.enable pcnfsd.enable raid.timeout raid.reconstruct_speed raid.scrub.enable wafl.maxdirsize wafl.root_only_chown
