Configure raid devices - logical volumes 6402

I have a MSA30 with an 6402 Smart Array controller.
Thru saconfig I have created 6 RAID 1 devices.
Which come up logical devices.

# RAID Size Status

0 1+0 69460 MB OK
1 1+0 69460 MB OK
2 1+0 69460 MB OK
3 1+0 69460 MB OK
4 1+0 69460 MB OK
5 1+0 69460 MB OK


I can not see any of these devices in SAM to create volume groups.
It comes up as one logical volume.

0/4/1/0/4/0.0.0 6 Unused -- 69460 HP

I need to create a volume group on each RAID slice.

Re: Configure raid devices - logical volumes 6402

If you created the new RAIDs online, you now need to create the device files (insf -e).

Check with "ioscan -fnCdisk".

Hope this helps!

Re: Configure raid devices - logical volumes 6402

ioscan lists the disks, but I can not see them in SAM.
It just shows one logical volume and only 72GB.
I have 6 RAID 1 logical sets.

Re: Configure raid devices - logical volumes 6402

SAM is showing 1 LUN with 6 pathes - this looks wrong. Patches needed? Check this.

Your LUN6 is missing!

You may just go ahead and use pvcreate, vgcreate, lvcreate ...

Hope this helps!

Re: Configure raid devices - logical volumes 6402

Ahhh the command line, the command line is your friend.
For some reason SAM did not pick up the disks.

After I created the physical volumes from command line, SAM had no problem.

ioscan -fnC disk
# pvcreate /dev/rdsk/c5t0d0
# mkdir /dev/vg01
# cd /dev/vg01
# mknod group c 64 0x010000
# vgcreate vg01 /dev/dsk/c5t0d0
# vgdisplay -v /dev/vg01

I did not have a problem with LUN 6, I just never created a RAID 0 device with it yet.
saconfig /dev/ciss5 -R 0 -p 2:8

Re: Configure raid devices - logical volumes 6402

LUN6 was showing NO_HW!

I would look for a current sam cumulative patch ... btw, 0 points = useless?

Hope this helps!
