Disk Troubleshooting
❖ To make all of the disks in the dynamic disk group available for use on the local
machine, deport the disk group on the remote machine and then import the dynamic
disk group on the local machine.
❖ To make one disk available for use on the local machine, remove the disk from its
dynamic disk group(on theother machine) and add it to a dynamic disk group on the
local machine.
❖ If the dynamic disk group is not imported on another machine, it can be necessary to
re-import the dynamic disk group and clear the host ID on all disks in the dynamic
disk group. You can do this by selecting the Clear Host ID option in the Import Disk
Group dialog box.
Caution If any ofthe disks inthe dynamic diskgrouparein use by anothermachine, this
command can cause the disks to be managed by two systems at the same time,
which can lead to corruption.
Disk State: Inactive
The disk appears to belong to a dynamic disk group, but is not active in the disk group.
The disk may have become (temporarily) inaccessible. Alternatively, the disk may have
been inaccessible at dynamic disk group import, but may be accessible now.
❖ Make sure that the physical disk is turned on, plugged in, and attached to the
computer. Repairany disk, controller, or cable problems. Scan the disks onthe system
(Rescan) to make sure that VxVM recognizes any newly attached hardware.
❖ It may be necessary to reattach the disk to its dynamic disk group with the Replace
Disk task.
After a successful reattach, volume recovery can be necessary.
❖ If the reattach fails and you want to free the disk space for use, you can use the
Initialize Disk task.
Caution This command overwrites the disk header and configuration information on
the disk. Anyvolumecopies orregionslocatedon thediskis notaccessibleafter
you reinitialize the disk.
Disk State: Foreign Owned
The disk is under the control of another disk management product. The disk is not
available for use with VxVM.
