Step Description (continued) Check 13 If using LVM PVLinks, add an alternate link to each physical volume in the volume F group. For example (using the example information from the ioscan in step 11): • To add an alternate link to /dev/dsk/c6t0d0, enter: vgextend /dev/vg06 /dev/dsk/c22t0d0 • To add an alternate link to /dev/dsk/c6t0d1, enter: vgextend /dev/vg06 /dev/dsk/c22t0d1 • To add an alternate link to /dev/dsk/c6t0d2, enter: vgextend /dev/vg06 /dev/dsk/c22t0d2 14 Ensure that the preferred path in the MSA for the LUNs is the same as the primary F PVLinks path. • In PVLinks, use the following command: vgdisplay -v /dev/ • In the MSA CLI, use the following command: show preferred_path • If the preferred path of the MSA LUNs is not the same as the PVLinks primary path, change the MSA path. In the MSA CLI, use the following command: set preferred_path 15 For the servers that were quiesced during the migration process, do the following from the server console: a. Reactivate all LVM volume groups on the MSA. b. Remount the file systems. c. Restart all I/O to the MSA storage LUNs. d. Restart all applications accessing the MSA. Troubleshooting To display and verify the status of a volume group, from the server console, enter: vgdisplay -v /dev/ To activate a volume group, from the server console, enter: vgchange -a y /dev/ To verify that device filenames and hardware paths did not change, from the server console, enter: ioscan -fnC disk To verify that the connection type is properly set for all HP-UX HBAs (profile=hp), from the MSA CLI, enter: show connections To verify that hard addressing has been set on direct-connect MSA controllers, from the MSA CLI, enter: show this_controller_hard_address To verify that access is granted to the LUNs on each MSA array controller, from the MSA CLI, enter: show acl Migrating from an active/passive single controller to active/active dual controllers in HP-UX environments 15
