Veritas VxVM TasksTRANSCRIPT
Veritas Volume Manager Tasks
Using slices to create minimal rootdg
veritas already installed
vxdctl add disk c0t0d0s4 type=simple
vxdisk -f init c0t0d0s4 type=simple
vxdg adddisk disk01=c0t0d0s4
You can now remove/move the remain disks from rootdg
veritas installed but not setup
vxconfigd –d ( if already started use vxconfig –m disabled)
vxdctl init
vxdg init rootdg
vxdctl add disk c0t0s0s4 type=simple
vxdisk -f init c0t0d0s4 type=simple
vxdg adddisk disk01=c0t0d0s4
vxdctl enable
rm /etc/vx/reconfig.d/state.d/install-db
Replace a disk in A5000
run “vxdiskadm” select option 4 to “remove a disk for replacement”1.run option 11 to take disk offline2.run luxadm remove_device [-f] <array>,<slot> (remember to do this both sides in a cluster)3.replace disk4.run luxadm insert_device <array>,<slot> (remember to do this both sides in a cluster)5.run vxdctl enable6.run “vxdiskadm” select option 5 to “replace a failed or removed disk”7.run "vxtask list" to make sure volumes have been sync'd if mirrors are involved8.
Restore a lost volume group (Volume manager 4.0)
Obtain a configuration file (if it exists):
# cd /etc/vx/cbr/bk/<diskgroup>.<diskgroupid>.<hostname>
You will see a file called "<diskgroupid>.<hostname>.cfgrec" this is the backed up configuration file for the disk
group
Display the configuration file in readable format: # cat <diskgroup>.<diskgroupid>.<hostname>.cfgrec | vxprint -D - -htr (This should show you all the
volumes under the group)
To precommit the changes run the following:
# /etc/vx/bin/vxconfigrestore -p <diskgroup>
To commit the changes after the precommit:
# /etc/vx/bin/vxconfigrestore -c <diskgroup>
