You are right, lau, in AIX the visibility of LUN and Physical Volume existence does not mean the Volume Group creation possibility. Our AIX Engineer came into the same issue. He also found the mapped LUNs (hdisk2,3,4) are not visible by the storage path manager: root@tsm64 /home/root# lsdev | grep hdisk hdisk0 Available Virtual SCSI Disk Drive hdisk1 Available Virtual SCSI Disk Drive *hdisk2 **Available 00-00-01 Other FC SCSI Disk Drive* * hdisk3 Available 00-00-01 Other FC SCSI Disk Drive* hdisk7 Available 00-00-01 MPIO Other FC SCSI Disk Drive *hdisk4 **Available 00-00-01 Other FC SCSI Disk Drive*
