Urgent !!! PV status : unavailable

[praveen..]

Hi,
I was installing some patches on 11iv1 system,
then i got this disk space error that i dont have free space in "/stand".

so i tried to extend it.
# swlist | grep -i JFS
B3929CA B.11.11 HP OnLineJFS

# lvextend -L 250 /dev/vg00/lvol1 (it is mounted on /stand)
Warning: rounding up logical volume size to extent boundary at size "256" MB.
lvextend: Not enough free physical extents available.
Logical volume "/dev/vg00/lvol1" could not be extended.
Failure possibly caused by contiguous allocation policy.
Failure possibly caused by strict allocation policy


then I check vg status of vg00.

You cannot increase the /stand without reinstalling using ignite backup.Because /stand need contiguous space allocation.

TO do a ignite backup recovery,

1.Check you have ignite ux installed in yuor system.If no,install from aplication cd or download and install latest vwersion of ignite-ux from hp site.

2.make a tape recovery backup using command

make_tape_recovery -A -a /dev/rmt/your-tape-drive -I -x inc_entire=vg00


3.restart your system

4.halt the boot sequence when it display "press any key in 10 seconds to STOP boot process"
search bootable devices (sea command at menu)
find tape and boot from tape

5.when it comes up, you need to select the disk/filesystem option and increase the size (HERE YOU ENTER NEW SIZE YOU WANT)of your /stand filesystem.

6.Start restore.

Praveen,

You can not extend /stand online, even if you have OnlineJFS installed.

First check the status of the "failing" disk.

# pvdisplay -v /dev/dsk/c3t6d0

# dd if=/dev/rdsk/c3t6d0 of=/dev/null bs=1024k

second lvreduce vg00/lvol1 back to the original size.

# lvreduce -L 128 /dev/vg00/lvol1

Robert-Jan

Praveen,

to know When a Volume Group Will Not Activate, what cause that problem, vgchange:

in this page, find (CNTL F)for "When a Volume Group Will Not Activate"

Hi all,
thanks for your suggestions,

now I am clening-up /stand directory sothat i can install the desired patch,

if i reboot the server then what will happen?

will i get all the file systems up? (bcoz i think these are mirrored disks)

I will install the ignite later for reinstalling the OS.

but 1-weeek before, i had extended the "/tmp" partition.

/dev/vg00/lvol6 2359296 66440 2275608 3% /tmp

i was able to extend the /tmp partition.

then why i am not able to extend /stand partition?

[inventsekar_1]

"Failure possibly caused by contiguous allocation policy.

/stand need contiguous space allocation.
no problem about /tmp.

[praveen..]

patch installation is asking for reboot the system...

if i reboot the server then what will happen?

will i get all the file systems up?

Praveen,

You may boot with primary disk since alternate disk shows unavailable and may be bad. Once system comesup, make sure that your alternate disk is available, if not, replace it.

Thanks,
Srini

[Robert-Jan Goossens_1]

Before you reboot, try to "vgsync /dev/vg00".

This will take a while.

Hi Praveen,

You are mixing problems!
a)I hope the first problem that you need to face on is the faulty disk. You can confirm that by using the command:
# ioscan -fnCdisk
You may have the disk device /dev/dsk/c3t6d0 referenced has: "NO_HW".
If it says: "CLAIMED" then just do a:
# vgchange -a y vg00
Just to refresh your kernel VG entry.
If not replace or ask your support for replacing the disk!

b)Your second problem is the stand extention. First I'm surprise about your /stand file system! Just do the command:
# cat /etc/mnttab | grep stand
For most installation we can see that /stand is a HFS instead of a VXFS filesystem, due to the boot handler(ISL) like here below!
/dev/vg00/lvol1 /stand hfs defaults 0 0 1154174415
In that condition you could not extend /stand in oder way that Igniting the server and reinstalling it with changes into the space allocation!
If you have an VXFS file system you can reboot in Volume Group maintenance and remove your swap space (in your case /dev/vg00/lvol2) then increase your /stand and recreate your swap space with the good OPTIONS into the that space left!

But if you are not an expert, I will not recommend that solution because you could of course loose your data and time spend is really growing for nothing!

My conclusion is do the disk replacement and do some cleanup in your /stand after that if is still not enough then do a recovery and reinstall your system with bigest /stand.

Cheers.

Hi Praveen,

First, I would like to inform to you that you have a problem for disk /dev/dsk/c3t6d0. Because the status is unavailable.

Can check with the commands below :

# ioscan -nfCdisk
Check whether the particular disk with NO_HW status or not

# diskinfo -v /dev/rdsk/c3t6d0
Check whether the disk still can give you the information

# dd if=/dev/rdsk/c3t6d0 of=/dev/null bs=1024k
Check if the disk gives you the IO errors

Second, you cannot extend the / and /stand on HP-UX since these file systems need a contigous space. Use Ignite/UX features OR re-install the OS to extend the file system. Meanwhile, you can try to housekeeping the /stand first.

So you need to fix the problem on the disk first meanwhile you can try to do a housekeeping on /stand (dont forget to backup first before housekeeping).

Hope this information can help.

Cheers,
AW

[praveen..]

I have cleaned-up the /stand.

and for PV status uavailable, I have opened a new thread "one disk of vg00 is unavailable.".


Thanks everybody.
