3. Perform a failover of the DR group.
4. Depending on the number of LUNs, do one of the following to prevent HP Secure Path from
detecting a failed disk:
• For individual LUNs, run spmgr quiesce –p path for each path visible to the LUNs.
• For all LUNs at once, run spmgr set –p off to turn off path verification for all LUNs
visible to the system.
Destination host procedure
If this is the first time that LUNs are being presented to the destination host, reboot the host to detect
the new LUNs. If a reboot is not required (LUNs have already been presented) and the paths are
quiesced, issue the spmgr restart all command to un-quiesce the paths.
Use one of the following procedures to perform a bootless DR group failover on the destination
host.
If you are not running LifeKeeper:
1. Issue the vgimport <volumeGroupName> <physicalVolumePath> command to make
the volume known to the system.
Example: vgimport vg01 /dev/sda1
2. Change the status of the LUNs to inactive using the vgchange <volumeGroupName> –a
y command.
Example: vgchange vg01 –a y
3. Mount the file systems.
Example: mount –t reiserfs /dev/vg01/lvol1 /mounts/lvol1
4. Start host I/O.
5. If the verification path is turned off, issue the spmgr set –p on command.
If you are running LifeKeeper 4.4.3 clusters:
1. If this is the first time LUNs are being presented to the destination host, you must build the
resource hierarchies for each LUN. See the documentation on the LifeKeeper CD.
2. Using the LifeKeeper GUI, take your resources out of service.
3. Start host I/O.
4. If the verification path is turned off, issue the spmgr set –p on command.
