Veritas Volume Manager 5.0 Release Notes
Known Issues
Chapter 1 25
• Setting site consistency on a volume
The vxvol command cannot be used to set site consistency on a volume unless sites and
site consistency have first been set up for the disk group. [530484]
• Adding a remote mirror
Adding a remote mirror to a new site for a site-consistent volume does not also create a
DRL log plex or a DCO plex at that site. The workaround is to use the vxassist addlog
command to add a DRL log plex, or the vxsnap command to add a version 20 DCO plex at
the specified site (site=sitename). [533208]
• Replacing a failed disk
It is not possible to replace a failed disk while its site is detached. 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, use the following commands to set the
correct site name on the replacement disk:
# vxdisk -f init disk
# vxdisk settag disk site=sitename [536853, 536881]
• Reattaching a site
Reattaching a site when the disks are in the serial-split brain condition gives an error
message similar to the following if the -ooverridessb option is not specified:
VxVM vxdg ERROR V-5-1-10127 disassociating sitename: Record not in disk group
Use the following commands to reattach the site and recover the disk group:
# vxdg -g diskgroup -o overridessb reattachsite sitename
# vxrecover -g diskgroup
• Site records are not propagated during disk group split, move or join
Split, join and move operations fail on a source disk group that has any site-confined
volumes. This is because site records cannot be propagated to a target disk group during
such operations.
One of the following messages is displayed as a result of a failed disk group split, join or
move operation:
There are volume(s) with allsites flag which do not have a plex on site
sitename.
