Hi Goru,
sounds like worst case ...

If you have enough free space on another machine you can copy the client images and configuration files, reinstall the ignite server and copy them back.

For Future you should implement a backup of the ignite server.

Shalom,

make_net_recovery

All you need is read-write access to an NFS share to write the image.

No SEP, I don't get you.

My point is if Ignite server itself crash what are the options to make it up as same server use for other application i.e it is not dedicated server.

I'm not sure if i got it right, you have 1 Ignite server (crashed), 5 clients which write their archives to the server.

Now you want to reinstall the server and save the client files before doing so - right?

Goru — Thu, 06 Aug 2009 10:34:50 GMT

No, image will save because it is on storage.
My question is how to recover ignite server + application server without doing fresh installation i.e how to take ignite backup of ignite server and recover it with recovery image.

I don't have external tape drive. I have blade server BL870c.

If ignite files and recovery archives are on the SAN and then you just need to present them to another server. Just with a little more config on the new server, you can then recover your original ignite server from the new one.

Hi

This is the worse case.You want to take full backup but you don't have the tape.I think there is the only way that make an one more backup server and take backup in this server.

If I will make other ignite client as ignite server and import existing volume group then what will be steps to restore original ignite server ? Can I take ignite server ignite on same server with make_net_recovery.

Please give me exact steps

Hi,

What we have done is, we have taken the ignite image of the ignite server and keep it on other server or client itself.

So that the other server or client will act as ignite server for the main server and we can recover if at all main server crashes.

Hi

<>

What is the use of that?? means if you take the ignute backup in the same server and your system crashes then no use of that.

Yes you can get ignite server recovery image on the same server. Here is some document for itanium, but i can't remember i tried it or not, anyway i think it should work:

1-)first install ignite-ux software to new server

2-)vgimport vg
#vgimport /dev/ignitevg /dev/dsk/ignitedisk
#mount /dev/ignitevg/lvignite /var/opt/ignite

3-)setup /etc/exports .
#vi /etc/exports
/var/opt/ignite/clients -anon=2
/var/opt/ignite/recovery/archives/client_name -anon=2,access=client_name
#exportfs â av

4-)setup /etc/hosts if necessary
#/vi/etc/hosts

5-)check bootps and tftp working

6-)enter old server MAC to /etc/bootptab.

7-)Change the recovery archive nfs_source to new server IP:
#vi /var/opt/ignite/clients/client_name/recovery/latest/archive_cfg
archive_cfg: nfs_source = "new_server_IP:/var/opt/ignite/recovery/archives/client_name

Sunny, you r missing one point I am saying that it is on SAN second if i will make other ignite client as ignite server (import of existing image VG) and want to restore original ignite server

Ganeshan, Can you give me steps ? How you do that recovery of ignite server.

Sunny123_1 — Thu, 06 Aug 2009 11:06:06 GMT

Cavdar suggestion sounds good but anyone experienced it?

Regarding to the software recovery handbook that should work.

Hi Again,

>>Ganeshan, Can you give me steps ? How you do that recovery of ignite server<<

Do you want the steps to recover the ignite server which is already crashed?

or

Do you want to know how to take the ignite image of ignite server itself?

Re: Ignite server crashed

Goru — Thu, 06 Aug 2009 11:34:40 GMT

Ganeshan, I want steps for how to recover crashed ignite server which image you keep on client.
