Volume status

This window displays volume information in the following formats:

• Default
• Verbose display
• RAID info
• Disk info

Default

The default window shows the following:

• volume name
• whether a volume is on-line or off-line
• the status of each volume, which can be:
  • normal: The volume is online without any problems.
  • initializing: You created the volume but it contains disks that are being zeroed by the filer.
  • growing: You added disks to the volume but the disks 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 group is missing two or more disks. Only an offline 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.

• the root volume

To see a volume status window with other types of information, press a button at the bottom of the display and then click on the Reload button. The following sections describe the displays other than the default.

Verbose display

The Verbose display shows similar information as the default display with the following additional information for each volume:

• option settings
• RAID group number
• RAID group status, which can be one of the following:
  • 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.

RAID info

The RAID info display contains the following columns for each volume:

• The RAID Disk column shows the 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."
• The HA.Disk_ID column shows the address for each disk in a RAID group. The address consists of two components: the host adapter number and the disk ID. For SCSI disks, the disk ID is the SCSI ID. For Fibre-Channel disks, the disk ID is the Fibre-Channel disk ID. For more information about locating disks based on the disk addresses, refer to the hardware guide for the disk shelf.
• The Used (MB/blks) column shows the number of megabytes and the number of blocks that can be used.
• The Phys (MB/blks) column shows the 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 info display includes information about the disk address and the amount of physical space.

Disk info

The Disk info display shows the disk addresses of the disks and the product information used by disk drive vendors to identify their disk drives.
