Step Description 14 Rescan all HBAs by entering the following command: # hp_rescan -a Check F NOTE: If LUNs that were not visible in the cat /proc/scsi/scsi display become visible after the hp_rescan -a, do the following: a. Run the pbl utility to probe the LUNs by entering the following: # cd /opt/hp/hp_fibreutils/pbl # ./pbl_inst.sh -i b. Restart the Linux host. c. Repeat step 13 and step14. 15 Re-mount the MSA LUNs on the Linux server. F 16 Repeat this migration procedure on each Linux server with access to the MSA. F 17 Migration is complete. F Consider the following optional procedure: By default, the firmware automatically distributes ownership of the LUNs between the two MSA controllers. If desired, manually set the preferred path for a LUN (controller ownership) as documented in the HP Array Configuration Utility user guide or the HP StorageWorks Modular Smart Array 1000/1500cs Command Line User Interface user guide, available on the MSA1000 website: http://www.hp.com/go/msa1000 and the MSA1500 website: http://www.hp.com/go/msa1500cs.
