GNR commands
Support and VDisk implementation GPFS features new commands for the GNR. Some
commands deliver the following monitor capabilities for the new subsystem components:
mmlsvdisk
mmgetpdisktopology
topsummary
mmlsvdisk
For this command, we list the help description in Figure 3-3. Typical output examples are
shown in Example 3-7 on page 171, Example 3-8 on page 172, Example 3-9 on page 172,
and Example 3-10 on page 174.
# mmlsvdisk -h
[E] Usage:
mmlsvdisk [--vdisk "VdiskName[;VdiskName...]" | --non-nsd]
or
mmlsvdisk --recovery-group RecoveryGroupName
[--declustered-array DeclusteredArrayName]
Figure 3-3 mmlsvdisk command flag description
The mmlsvdisk command lists the GNR topology configuration. The following input and
output values are shown:
Command: mmlsvdisk
Flags:
– --non-nsd: Displays non-NSD type disks and LOG disks.
– --vdisk "vdisk_name": Displays VDisk detailed information about the <vdisk_name>.
– --recovery-group "recovery_group_name": Displays VDisk information about the
<recovery_group_name>.
Outputs:
[no-flags]
<vdisk_name> <RAID_code> <recovery_group_name> <declustered_array>
[--non-nsd]
Same as with [no-flags] but only for LOG VDisks, as shown in Example 3-8 on page 172.
[--recovery-group]
vdisk:
name = "<vdisk_name>"
raidCode = "<RAID_code>"
recoveryGroup = "<recovery_group_name>"
