How to create a persistent special file on HPUX 11.31 !!

[iazuarah]

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

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?

The problem was solved !!. My storage Administrator dettach and attach this lun again.After this action, i execute the scsimgr command and the 4 lun appears with the persistent special file.

# scsimgr -v -f replace_wwid -C lunpath -I 126

Regards !!
