Before You Begin
Check Prerequisites for Creating Solaris Volume Manager Components.
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes and choose a volume. Choose Action⇒Properties. Then, choose the Hot Spare Pool panel. Finally, choose Attach HSP. For more information, see the online help.
Use the following form of the metaparam command:
# metaparam -h hot-spare-pool component
Specifies to modify the named hot spare pooll.
Specifies the name of the hot spare pool.
Specifies the name of the submirror or RAID-5 volume to which the hot spare pool is being associated.
See the metaparam(1M) man page for more information.
Example 17-4 Associating a Hot Spare Pool With Submirrors
In the following example, the -h option associates a hot spare pool, hsp100, with two submirrors, d10 and d11, of mirror, d0. The metastat command shows that the hot spare pool is associated with the submirrors.
# metaparam -h hsp100 d10 # metaparam -h hsp100 d11 # metastat d0 d0: Mirror Submirror 0: d10 State: Okay Submirror 1: d11 State: Okay ... d10: Submirror of d0 State: Okay Hot spare pool: hsp100 ... d11: Submirror of d0 State: Okay Hot spare pool: hsp100 ...
Example 17-5 Associating a Hot Spare Pool With a RAID-5 Volume
In the following example, the -h option associates a hot spare, hsp001, with a RAID-5 volume,d10. The metastat command shows that the hot spare pool is associated with the RAID-5 volume.
# metaparam -h hsp001 d10 # metastat d10 d10: RAID State: Okay Hot spare pool: hsp001 ...
Before You Begin
Check Prerequisites for Creating Solaris Volume Manager Components.
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node and choose the volume. Choose Action⇒Properties. Then choose the Hot Spare Pool panel. Detach the unwanted hot spare pool and attach the new hot spare pool by following the onscreen instructions. For more information, see the online help.
Use the following form of the metaparam command:
# metaparam -h hot-spare-pool-name RAID5-volume-or-submirror-name
Specifies to modify the hot spare pool named.
Specifies the name of the new hot spare pool, or the special keyword none to remove hot spare pool associations.
Specifies the name of the submirror or RAID-5 volume to which the hot spare pool is being attached.
See the metaparam(1M) man page for more information.
Example 17-6 Changing the Hot Spare Pool Association
In the following example, the hot spare pool, hsp001, is initially associated with a RAID-5 volume,d4. The hot spare pool association for the volume is then changed to hsp002. The metastat command shows the hot spare pool association before and after this change.
# metastat d4 d4: RAID State: Okay Hot spare pool: hsp001 ... # metaparam -h hsp002 d4 # metastat d4 d4: RAID State: Okay Hot spare pool: hsp002 ...
Example 17-7 Removing a Volume's Hot Spare Pool Association
In the following example, the hot spare pool, hsp001, is initially associated with a RAID-5 volume, d4. The hot spare pool association is then changed to none, which indicates that no hot spare pool should be associated with this volume. The metastat command shows the hot spare pool association before and after this change.
# metastat d4 d4: RAID State: Okay Hot spare pool: hsp001 ... # metaparam -h none d4 # metastat d4 d4: RAID State: Okay Hot spare pool: ...
