"missing" clariion LUNs in HP-UX

[Rommel T. Misa_2]

We are trying to create vgs on our clariion cx 3-80 and when I try to do so i got these errors:

# pvcreate -f /dev/rdsk/c12t0d2
Physical volume "/dev/rdsk/c12t0d2" has been successfully created.
# mkdir /dev/vg34
# mknod /dev/vg34/group c 64 0x340000
# vgcreate /dev/vg34 /dev/dsk/c12t0d2
vgcreate: Cannot open the control file "/dev/vg34/group":
No such device

Also, not all configured disks in the cx 3-80 are not seen either when running ioscan or via SAM. We are running an rp7440 with hp-ux 11i v1.

Hope you can help me...

Thanks in advance,
Rommel

Shalom Rommel,

Afte this step:

mknod /dev/vg34/group c 64 0x340000

echo $?

# We need a zero response cde.

cd /dev/vg34
Now mknod

Also:
See that LUN assignment is to the proper world wide name (WWN)

can you do a ll /dev/* |grep 340000 to see if the numbre is not in used by a other group file?

Hello guys,

Thanks for the response. We have solved the vg creation issue by using another minor number to be associated with the volume groups to be created.

One last issue is with the undiscovered EMC Clarion disks.

Has any of you experienced this? I tried running insf -e and ioscan -fnC disk to no avail.

Hope you could help me with this. Thanks again.
