Recover OS

pgaidai — Thu, 14 Mar 2013 01:26:33 GMT

Hello!

OS - HP-UX 11.23 based on the two disks in RAID-0. One day ago, one of the disk has broken down.

We backup our systems using EMC networker.

How can I correctly restore from backup? Because, after having istalled new system and networker clinet, i recovered all files. then i rebooted os but os failed to be booted.

I think, problem is in the discrepancy between LVM settings of the new OS and previously backuped files.

Help me, please, to solve this situation.

P.S. This thread has been moved from HP-UX > System Administration to HP-UX > ignite - HP Forums Moderator

HP-UX OS should be backed up with Ignite-ux.

I dont know how you used Networker to restore the OS files.

The idea should be a cold isntall, and make the configuration accordingly if you dont have a Ignite backup.

Let's see ...

You have an rx2620 with an smart array sa6400, so only a RAID 0? Bad idea!

The you cold-installed the OS and restored all (!) the data?

Look at this

...

/sbin/rc2.d/S131ipfboot[5]: ps: not found
/sbin/rc2.d/S131ipfboot[5]: grep: not found
/sbin/rc2.d/S544cfservd[65]: hostname: not found
/sbin/rc2.d/S546syslog-ng[61]: hostname: not found
interpreter "/bin/sh" not found
file link resolves to "/usr/bin/sh"
...

Something went really wrong during restore.

Consider to boot into single user (if possible) and check (vgdisplay, etc - if vg00 is OK or not) or better start over with cold-install and restore.

Better use ignite to backup your OS next time!

Oh.. i know this.
This server is an additional node of the ORACLE testing cluster.

Maybe you are right. Because i recovered files in multi-user mode.

Can you give me links to the useful documentation about backuping hp-ux using ignite?
