VxVM basic question - how to add a disk

[David Freer_1]

Fresh HPUX install on this system after several disk crashes and we're now ready to configure VxVM. Only problem is, it can't see two of the newly replaced disks. ioscan & diskinfo see them OK but:

# vxdisk list
DEVICE TYPE DISK GROUP STATUS
c4t0d0 auto:hpdisk rootdisk01 rootdg online
c4t1d0 auto:cdsdisk - - online
c4t2d0 auto:cdsdisk - - online
c4t3d0 auto:cdsdisk - - online
c4t5d0 auto:cdsdisk - - online
c4t6d0 auto:cdsdisk - - online
c5t8d0 auto:cdsdisk - - online
c5t9d0 auto:cdsdisk - - online
c6t1d0 auto:cdsdisk - - online
c6t2d0 auto:cdsdisk - - online
c6t3d0 auto:cdsdisk - - online
c6t4d0 auto:cdsdisk - - online
c6t5d0 auto:cdsdisk - - online
c6t6d0 auto:cdsdisk - - online
c7t8d0 auto:cdsdisk - - online
c7t9d0 auto:cdsdisk - - online
c7t10d0 auto:none - - online invalid

No sign of c4t4d0 or c6t0d0. There are no /etc/vx/*.exclude files and vxdctl enable doesn't seem to find the disks as I was led to believe.

/etc/vx/disk.info doesn't include the disks which I believe is the underlying fault but if this file has to be manually edited then I will need guidance as to how to get the appropriate information.

Cheers,

David.

Hi Davis,

did you try vxdiskadm , replace a disk option?

Robert-Jan

[David Freer_1]

Sorry, no good:

VxVM INFO V-5-2-396
There are currently no devices that are failed or removed.

[Robert-Jan Goossens_1]

ok,

Try this.

# mv /etc/vx/disk.info /etc/vx/disk.info.old
# vxconfigd -k

To create a new info file.

Robert-Jan

[David Freer_1]

Already tried that...sorry, still no good.

[Siju Vadakkan]

try following steps

1. vxdisk scandisks
2. vxdisk list

if still the problem persists do the following steps.

mv /etc/vx/disk.info /etc/vx/disk.info.old
vxconfigd -k -m enable
ioscan -fnC disk
vxdisk list

[David Freer_1]

Further information:

It looks like 3 disks are unavailable, I had forgotten about c5t10d0. All three were recently replaced and all 3 are the same type, i.e. FUJITSU MAW3073NC

[Robert-Jan Goossens_1]

and if you add them with

# /etc/vx/bin/vxdisksetup -i c4t4d0

Robert-Jan

[David Freer_1]

# /etc/vx/bin/vxdisksetup -i c4t4d0

Found the problem...now how do we fix it?
Veritas sees c4t3d0 as ALL of the replaced disks...

try following steps

1. vxdisk scandisks
2. vxdisk list

if still the problem persists do the following steps.

mv /etc/vx/disk.info /etc/vx/disk.info.old
vxconfigd -k -m enable
ioscan -fnC disk
vxdisk list

[Siju Vadakkan]

Hope Following steps will solve ur issue

[David Freer_1]

As previously mentioned in this thread, these steps do not work.

[Darrel Louis]

David,

Check if your VxVm is Licensed
vxlicense -t VxVM
vxlicense -p

ioscan -fn
insf -e
vxdctl enable

vxdg free
vxdg list
vxdisk -o alldgs list
vxdisk -s list c4t4d0
/etc/vx/bin/vxdisksetup -i c4t4d0

Run vxconfig in debug mode:
vxconfigd â k â m enable â x9 â x log >/var/tmp/vxconfigd.log 2>&1

See also http://www.docs.hp.com/hpux/onlinedocs/5187-1374/5187-1374.html

GoodLuck
Darrel

[David Freer_1]

Issue is now sorted, thanks to all those who replied. The problem was that vxddladm listjbod showed the system was looking at the first 10 characters of the serial ID for Fujitsu disks, not the full 12 and in our case the first 10 characters were all the same so it was being seen as multiple paths to the same disk.

# vxddladm rmjbod vid=FUJITSU
# vxddladm addjbod vid=FUJITSU length=12
# rm /etc/vx/disk.info

and a reboot solved the problem.

[David Freer_1]

See above for solution.

I am speaking out of ignorance here. I haven't used VXVM.

From your question, it looks a lot harder to use than traditional logical volume managment (LVM).

Are the commands really so goofy?
