You can use the-whitelist parameter to obtain the wwid of a disk in RHEL 6: [root @ db1 ~] # Scsi_id -- whitelist/dev/sdg 360060160a2212f00f8139df761ece111 www.2cto.com you can use a shell command to obtain the wwid of all the system disks: # for I in 'cat/proc/partitions when awk {'print $ 4'} then grep sD'; do echo "###$ I: 'scsi _ id -- whitelist/dev/$ I '"; done in RHEL 5 can obtain the disk wwid in the following way: # for I in 'cat/proc/partitions when awk {'print $ 4'} then grep sD'; do echo "###$ I: 'scsi _ id-g-u-s/block/$ I '"; in addition, the multi-path configuration file in RHEL 6 also changes: # multipath.
