Cmdlet: Set-NaFcpClusterMode
NAME
Set-NaFcpClusterMode
SYNOPSIS
Set the current cfmode setting for the system.
SYNTAX
Set-NaFcpClusterMode [-Mode] <String> [-Force] [-Controller <NaController>]
[<CommonParameters>]
DESCRIPTION
Set the current cfmode setting for the system. This setting controls how the
cluster behaves during a takeover/giveback. It also controls if the filer s
hould use multiple virtual target adapters per physical target adapter. fcp
service must be stopped before executing this API. If cfmode is set to 'dua
l_fabric' the filer connects to the FC fabric in loop mode and all initiator
s need to have multipathing software. If cfmode is set to 'mixed' the filer
connects to the FC fabric in loop mode and assigns multiple virtual identiti
es to each physical FC target adapter. If cfmode is set to 'partner' the fil
er connects to the FC fabric in ptp mode. The B-port on each FC target adapt
er proxies commands for the partner over the cluster interconnect. If cfmode
is set to 'standby' the B-port is in standby mode and takes over the partne
r WWNN and WWPN during a cluster takeover. A ptp connection is used in this
case. If cfmode is set to 'single_image' the filer connects to the FC fabri
c in ptp mode by default but is configurable, and all luns in the cluster ar
e visible on all FC target ports. In this mode all hosts require multipathin
g software.
On filers with only one FCP target port the valid cfmodes are 'dual_fabric',
and 'single_image'
On filers with more than FCP target port the valid cfmodes are 'mixed', 'par
tner', 'standby' and 'single_image'.
When setting the cfmode to 'single_image' configuration checks are performed
. If these checks fail an EPERM error will be returned. See the 'TestNaLun
Config -CFMode' cmdlet for more information.
