You must first reattach the site and recover the disk group by running these commands:
# vxdg -g diskgroup reattachsite sitename
# vxrecover -g diskgroup
The vxdiskadm command gives an error when replacing disk on which the site tag had been
set. Before replacing such a failed disk, run the following commands to set the correct site
name on the replacement disk:
# vxdisk -f init disk
# vxdisk settag disk site=sitename
• Problem
Reattaching a site when the disks are in the serial-split brain condition gives an error message
similar to the following if the -o overridessb option is not specified:
VxVM vxdg ERROR V-5-1-10127 disassociating sitename: Record not in disk group
Workaround
Use the following commands to reattach the site and recover the disk group:
# vxdg -g diskgroup -o overridessb reattachsite <sitename>
# vxrecover -g diskgroup
Snapshot and Snapback Issues
The following snapshot and snapback issues are known:
• Problem
It is recommended that you not use the snapshots of the root volume as a bootable volume.
You can take a snapshot to preserve the data of the root volume, but this snapshot will not be
bootable.
Workaround
Restore the data from the snapshot to the original root volume before booting the system with
the preserved data.
• Problem
When taking a snapshot of a SFCFS file system, the following warning message might appear:
VxVM vxio WARNING V-5-0-4 Plex plex detached from volume volume
Workaround
No action is required. You can ignore this message.
• Problem
Do not add cache volumes (used by space-optimized instant snapshots) to volume sets. This
causes data corruption and system panics.
Workaround
No workaround exists for this problem.
• Problem
A file system is not affected when a snapshot is taken. However, if a SFCFS file system is not
mounted, it is likely that the fsck of the snapshot will take longer than is usually necessary,
depending on the I/O activity at the time of the snapshot.
Workaround
