Hello,
I have a strange situation with 1 disk from my san. My storage administrator delivery 4 luns (by 2 paths) for the hpux 11.31 box. When i execute the ioscan command have the next output:
# ioscan -m dsf
??????????? /dev/rdsk/c20t9d5
/dev/rdsk/c18t9d5
/dev/rdisk/disk169 /dev/rdsk/c20t9d6
/dev/rdsk/c18t9d6
/dev/rdisk/disk170 /dev/rdsk/c20t9d7
/dev/rdsk/c18t9d7
/dev/rdisk/disk171 /dev/rdsk/c20t10d0
/dev/rdsk/c18t10d0
One disk is missing !!!. When i check the total disks that i have in the server the output is (the four new disks are marked):
# ioscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description

/dev/dsk/c20t10d0 /dev/rdsk/c20t10d0
The persistent special file that involve the c20t9d5 and c18t9d5 disks is missing. How can create this persistent special file ??. Can i use the disk168 special file for this luns ??
Thanks in advance !!

Have you tried running 'insf -e' to (re)create device files?
