Thanks

There is alot of information out there...but it would depend on what kind of DR you are looking for.
DR can be as cheap as simply getting a replacement server (if that model is still available) and applying your make_recovery tape to rebuild the O/S then apply your backup tapes to restore data..

Or much more like:

High Availablity Clusters aka MC/SG depending on what your looking for...local failover; campus failover; metro failover or long distance failover. Which involves using something like HP's Continue Access or EMC's SRDF to sync disk arrays between sites.

So it can be Quick & Cheap or Complete & Expensive...Depends on what mgmt wants.

Rgrds,

Take a look at the HP-UX Software Recovery Handbook

Any DR procedure begins with the reinstallation or porting of the O/S and this procedure begins and ends with ignite. Some people make an O/S image when the O/S changes, other do it every Friday night via a cron script. Here is a URL:

Bear in mind the clone ignite procedure since you'll have to consider porting to another server. For this to successfully port, you have to have a DR server of the same HW class. You can't get around this. And with the emergence of Itanium CPU's, this becomes an even bigger consideration.

Successful backups of your data should be obvious. BCV's via EMC Timefinder or Business Copy Volumes via HP's XP disk arrays and SAN's should also be reviewed. However, people have been exporting their daily oracle changes and ftp'ing up to there DR site for years. It???s all about recovery time. BCV's are more seamless while ftp'ing probably takes a few hours to restore. This is what a High Availability environment is all about and Service Guard. With Service Guard continental cluster its possible to failover to a DR site 100 miles or more away. See Dark Fibre, a very expensive WAN implementation.

Hi

i think that the best mthod to get a plan to Disaster Recovery in Hp-Ux is to use the ignite software that isa free of charge .

in the ignite software there is two metod to go .

1. one is just to install the software and to do a :
make_tape_recovery -A -a device file .

this will backup your system ( system disk only ) to a tape drive and if your system has problem you can restore your system without any problem .

this metod is very ease to use.

2. to config a ignite server and to do make_net_recovery or to do a gloden image to your system .

you can look for info about ignite on this link :
http://www.software.hp.com/products/IUX/docs/sysadm.html

and you can also download the software from this link :

Ignite recovery the vg00 but in case that you have vg01 and vg02.
Thanks

Ignite is not intended to be the only answer. It should be used in conjunction with regular backup procedures for not root volume data. You can use fbackup or purchase other backup products, but you have to have a procedure in place. Ignite is designed just to recover your root volume group so you can then restore the rest of your data and get going again.

Sorry - make that "non-root-volume data"

Install from IUX tape
Reconfigure LAN cards to match new hardware.
Rebuild none root vgs (we have this part automated, well you have to for large systems)
Install tape patches
Install Backup s/w (not required for fbackup, cpio, etc)
