RAID

 This window contains three panes for displaying disk, volume, and RAID information.

Disks

The following list describes the disk information in each column of the disk pane.

HA.ID
  • HA is the host adapter number, which is the same as the number of the slot in which the disk adapter card is installed. For example, 9 means the adapter is installed in slot 9. If there are multiple interfaces on one adapter card, the interfaces are named a and b.
  • ID is the disk number, which starts from 0.
HA SHELF BAY
  • HA is the same host adapter number as in the HA column.
  • SHELF is the number of the disk shelf attached to the host adapter. Multiple disk shelves can be connected to a disk adapter interface if the disk adapter is a differential SCSI adapter or a Fibre Channel adapter. The disk shelf number starts from 0.
  • BAY  is the number of the disk slot in the disk shelf, which starts from 0.
CHAN
Channel number for a Fibre Channel disk.
Disk Vital Product Information
Product information used by disk drive vendors to identify their disk drives.

For more information about physically locating a disk, see the hardware guide appropriate to your disk shelf model.

Cluster considerations

The output for a filer in a cluster includes disks on both fibre channel loop A, which the local filer owns,  and loop B, which the partner owns.

Volumes

The Volumes pane has two sections: the first one displays volume configuration and status information; the second one displays disk usage information.

Volume configuration and status information

The following list describes each column of the first section of the Volumes pane:

Volume
Name of each volume on the filer.
State
Whether a volume is on-line or off-line.
Status
Status of each volume, which can be one of the following values:
  • normal: The volume is on-line without any problems.
  • initializing: You created the volume but it contains disks that are being zeroed by the filer.
  • degraded: The volume contains one or more RAID groups that are in degraded mode. Degraded mode means that one data disk is missing in the RAID group.
  • reconstructing: The volume contains one or more RAID groups that are reconstructing data.
  • offline pending: You specified that the volume will go off-line at the next filer reboot.
  • partial: The volume is missing one or more RAID groups, or one of its RAID groups is missing two or more disks. Only an off-line volume can have this status.
Unless the volume status is normal, the status field for a volume can display more than one value. For example, the status of a volume can be degraded,reconstructing, which means that one or more RAID groups are in degraded mode and one or more RAID groups are reconstructing data.
Options
Settings of the volume options.
RAID group
For each RAID group in the volume, the following types of information are listed:
  • RAID group number
  • RAID group status, which can be one of the following values:
    • normal: All disks are up and running.
    • partial: The RAID group is missing two or more disks.
    • degraded: The RAID group is missing one data disk.
    • reconstructing: The RAID group is reconstructing data.

Volume disk usage information

The following list describes each column of the second section of the volumes pane:

Filesystem
name of the file system. It can be a path name to a volume or a path name to the snapshot in a volume.
kbytes
number of kilobytes of disk space for the file system.
  • For an active file system, this number doesn't include the parity disk, hot spare, snapshot reserve, and about 10 percent of the disk space reserved for efficiency. Therefore, this number is smaller than the total amount of disk space you installed for the volume.
  • For a snapshot, this number is the same as the amount of disk space reserved for snapshots in that volume.
used
number of kilobytes used by the file system.
avail
number of kilobytes available to the file system.
capacity
percentage of disk space used in the volume.
Mounted on
Same information as in the Filesystem column.

RAID

The following list describes each column of RAID pane:

RAID Disk
Types of disks in each RAID group, which can be data or parity. If a disk is being added to a RAID group, the disk type is shown as pending.
HA.ID
  • HA is the host adapter number, which is the same as the number of the slot in which the disk adapter card is installed. For example, 9 means the adapter is installed in slot 9. If there are multiple interfaces on one adapter card, the interfaces are named a and b.
  • ID is the disk number, which starts from 0.
HA SHELF BAY
  • HA is the same host adapter number as in the HA column.
  • SHELF is the number of the disk shelf attached to the host adapter. Multiple disk shelves can be connected to a disk adapter interface if the disk adapter is a differential SCSI adapter or a Fibre Channel adapter. The disk shelf number starts from 0.
  • BAY is the number of the disk slot in the disk shelf, which starts from 0.
CHAN
Channel number for a Fibre Channel disk.
Used (MB/blks)
Number of megabytes and the number of blocks that can be used.
Phys (MB/blks)
Number of megabytes and the number of blocks present on the disk. These numbers can be greater than the numbers in the Used (Mb/blks) column because disks are "right-sized."

For each spare disk, the RAID information display includes information about the disk address and the amount of physical space.

Cluster considerations

In a cluster, the window displays information about both filers:

  • For each filer, the display includes disks on both FC-AL loop A and FC-AL loop B.
  • The information about disks on FC-AL loop A is the same as for filers not in a cluster.
  • The information about disks on FC-AL loop B is for hardware only; it includes only information about the adapters supporting the disks. It does not show whether a disk on FC-AL loop B is a file system disk, spare disk, or parity disk, nor does it show disk usage.
