This step applies to DMP.
If any path to the target disk has SCSI reserve ODM attribute set, then change the attributes to release the SCSI reservation from the paths, on a restart.
If a path has the reserve_policy attribute set, change thereserve_policy attribute to no_reserve for all the paths.
# lsattr -E1 hdisk557 | grep res
reserve_policy single_path
Reserve Policy True
# chdev -l hdisk557 -a reserve_policy=no_reserve -P
hdisk557 changed
If a path has the reserve_lock attribute set, change the reserve_lockattribute to no.
# lsattr -E1 hdisk558 | grep reserve_lock
reserve_lock yes
Reserve Device on open True
# chdev -l hdisk558 -a reserve_lock=no -P
