Hot-relocation:
in addition to using disks as hot spares, the hot relocation facility
can also use any available free space in the disk group. If no disks have
been designated as spares when a failure of a redundant object occurs, VxVM
automatically uses any available free space in the disk group in
which the failure occurs. If there is not enough spare disk space,
a combination of spare space and free space is used. After a disk
is repaired, you can move all the hot-relocated subdisks back to
the original disk using the vxunreloc(1M) utility. | No action needed for hot
relocation. To move hot-relocated subdisks back to the
original disk: vxunreloc disk_name |
Rename a disk | vxedit rename old_diskname new_diskname |
Offline a disk. | vxdisk offline disk_name Alternatively, menu option 12 of vxdiskadm performs this task. |
Online a disk. | vxdisk online disk_name Select menu option 10 of vxdiskadm. |
Evacuate a disk. | vxevac -g disk_group medianame new_medianame |
Replace a disk. | Select menu option 4 of vxdiskadm. |
Recover volumes on a disk. | vxrecover -g disk_group vol_name medianame |
Display a DMP node. | vxdisk list meta_device |
Rename a disk
group. | vxdg -tC -n newdg_name |
Rename a volume. | vxedit -v rename name newname Update the /usr/fstab file with the new name. |
Add a DRL log to a volume. | vxassist addlog vol_name |
Create a snapshot copy
of a volume. | vxassist snapshot vol_name temp_vol_name |
Recover a volume. | vxrecover -g disk_group volume medianame vxmend fix clean plex_name |
Repair a mirror | vxplex att plex_name |
Disable a mirror | vxplex det plex_name |
Remove a log from a volume. | vxassist remove log vol_name |
Move a subdisk. | vxsd mv old_subdisk new_subdisk |
Split a subdisk. | vxsd -s size splitsubdisk new_subdisk1 new_subdisk2 |
| Join subdisks. | vxsd joinsubdisk1 subdisk2 new_subdisk |
