vxdisk list will show the disk reservations on the LUNs. vxdisk -o listreserve list Disk_1 The SCSI3-PR information will show up at the bottom or you will see "no registered pgr key"
In 5.0, there is also the vxdiskpr command which can clear the SCSI3-PR keys. use the dmp device vxdiskpr clear /dev/vx/dmp/Disk_1s2 Obviously, clearing the SCSI3-PR keys should not be done without understanding the consequences to the protection of your data. We have seen cases where hardware vendors have set keys that nobody could clear. And sometimes keys must be cleared on the host that set the key.
