Hi All
I hvae one D Class machine[D370], with 10.20 OS configured "Disk Array 12H".
Now i want to reinstall the OS on that machine so i planned to delete the configured LUN in that Disk Array, when i tryed to delete the LUN from the Diskarray it's giving the following error message

# /opt/hparray/bin/arraycfg -L 0 -d 0000000E915E

Error in command execution, "RMT_ARMERRORSTATUS_MSG"

ARMERR : ERR_COMMAND_FAILED
ARMERR Qual : DELETE_LUN
MODULE_CODE_ID : SUBSYSTEM
OS LAYER ID : HP-UX
COMMAND STATE : An OEM errno was returned
ERROR NUMBER : 16
OEM MESSAGE : "Device busy"

arraycfg: Error in command execution.

Can anybody help me out to solve this problem.

Hi Prasath,

Try

# /opt/hparray/bin/arraycfg -dL 0000000E915E

LUN # should follow the -L.

HTH,
Jeff

Sorry....you obviously did that....
If you're trying to delete the LUN containing vg00 - forget it - you'll never be able to. It will *always* be busy.
After rereading your post I'd advise you just install the OS & don't bother deleting the LUN.....just overwrite it.
You are installing/reinstalling an OS, right?
Just run 2 make_recovery tapes in case you might need an org file.

Rgds,
Jeff

Hi Jeff

The whole disk array mounted as follows.
/dev/vg101/lvol1 66093384 21243145 41545569 34% /ignite.

3 LUN was created in that disk array.

But we don't want it as a sigle mount point. That's y i want to delete the LUN in that before going for OS installation.

If i install OS in that machine without deleteing LUN then how can i create LUN or over write.

Can you pls tell the procedure.

Thanks in Advance

If you really want to kill the LUN use Autoraid's front panel. It's the simplest way

I would definitely recommend a backup before any of this. Try unmounting your mount points, then removing the VG that refers to the 12h LUN. Then you shouldn't have any more problems deleting.

Good Luck.

/dev/vg101/lvol1 66093384 21243145 41545569 34% /ignite.

cd /
umount /ignite
vgexport vg101 (note: vg101 now doesn't exist)
(if you want to get it back you can always vgimport)

but, delete the lun now as you have attempted already. If it doesn't work, arraydsp -a, the LUN 0 could just be a "phantom lun"

Later,
Bill
