OS backup of rp3440 HP UX

[ganzsp]

Hai,
we have a rp3440 HP server which doesn't have a tape drive as well as storage disk and ignite server.

I have juz installed ignite ux 7.5 in one of the available server which has a tape drive to take make_net_recovery.Has done things as below,

1.Installed ignite-ux 7.5 in server A
2.mkdir -p /var/opt/ignite/recovery/archives/serverB
3.chown bin:bin /var/opt/ignite/recovery/archives/serverB
4.exportfs -av

In serverB

1. umask 022
2. make_net_recovery -s serverA -x inc_entire=vg00

it throwed space error.
I made a soft link as follows,

In serverA
# ln -s /var/opt/ignite/recovery/archives/serverB /FS/server B
#chown bin:bin /FS/serverB
#exportfs -av

Tried the same in server B.
but again got space error.

ERROR: Not enough space for archive.
/var/opt/ignite/recovery/arch_mnt on local needs 5660625 kbytes free.
There are 255696 kbytes free.

i have no space in vg00 to increase. Please guide me what i have to do take OS back up of this server.

#is there any setup to try it again and take backup else
#have to set a new ignite server with huge vg00 space else
#new tape drive/is it available for rp3440 server else
#it has only a dvd drive.so is that possible.

any other gud option??!. Please let me know i'm working out on this for the past two dayz but havent found the solution yet.

Thanks in advance i was lookin up for a quick response as this is critical for me now to do patch upgradaton on ServerB whose OS backup is not happening.. :(

Thanks

Do not place the archives directly in vg00!

Create a new lvol and mount it, let's say to

/var/opt/ignite/recovery/archives

This will give you enough space to store the archives.

hi ganzsp,

You will have to nfs mount the remote directory to be able continue with your backup.

Make sure that this link does not affect your production data just in case you have significant activities at the time of backup.

Good luck!

kind regards

Hai,

i tried but gzip:file too large made it fail..

anyway to gzip files >2GB to complete this successfully.

Hi,

>make_net_recovery -s serverA -x inc_entire=vg00

You could try without using the option [-x inc_entire=vg00]. It would only copy the minimal OS.

or
use make_net_recovery -i (interactive mode so that you can choose the ones you need to copy)

or
as a temporary solution use fbackup, because in anyway at least you need a backup!!

If you go for fbackup do as below:
Make temporary trust (.rhosts) with the other server.

cd /
fbackup -vf remote-server:/dev/rmt/0m -i .

If you can unmount other VGs, it would be easy with the above command. Otherwise, use a graph file (man fbackup) with only vg00 so that it will only copy the files in vg00.

Shalom,

All ignite clients build temporary files in the /var/filesystem.

/var/opt/ignite/recovery/arch_mnt on local needs 5660625 kbytes free.
There are 255696 kbytes free.
ERROR: Not enough space for archive.

There needs to be sufficient space for that on the /var filesystem

The archives themselves should not be created in the volume group being backed up. In that case Ignite tries to backup the backup, that is a circular situation that can not complete.

Hai,

I have made space change and only file too large error is the obstacle.

gzip: stdout: File too large
ERROR: The gzip command failed (exit status 1).
ERROR: The gzip command failed (exit status 1).

ERROR: The make_sys_image command failed. The system recovery archive will
not be created.

======= 05/12/08 06:47:26 EDT make_net_recovery completed unsuccessfully

I have gzip version 1.3.5 in both the servers.Please let me know how to resolve it.

Is fbackup is ok with remote server?! through NFS?? I guess OS backup is for disaster recovery and ignite backup is often suggessted.Please advise on the same.

The FS /var/opt/recovery/archives/arc_mnt in Server A is set to largefiles in /etc/fstab and umounted and mounted again.

still facing same error. :(

Thanks

If this is started from cron job check for patch PHCO_31198.

What is your gzip version. May bei t has 2GB limit

which gzip
gzip -v

May be you can move the >2GB files to another vg and try make_net_recovery again.

The ignite is always better for DR and the OS recovery.

fbackup is an alternate temporary solution.

Hai all,

Thanks for your valuable informations.I have done with backup and patch upgrade. but when the system is up one of our FS is not mounted.It is available in /etc/fstab
but when i try to mount i get as below

# mount -F vxfs /dev/vg01/lv_ins1 /ins1
vxfs mount: /dev/vg01/lv_ins1 is already mounted, /ins1 is busy,
or allowable number of mount points exceeded

I was not able to mount and it is not present when i use BDF command.

Can any one get me what went wrong and how to overcome this.

Thanks
Ganzsp

[Mridul Shrivastava]

Make sure that someone is not working under /ins1 directory.

Check the output of fuser -u /ins1 command.

[ganzsp]

hai done,
it is used by few applications that are automated.

Thanks :)

Done with Make_net_recovery setting remote FS with large File size
