Checking two systems

[khilari]

Hi people, how are you. I have two rp7470's and i want to know what can i do to check them before i could put them in production environment???

Secondly, about disaster recovery. I want to use ignite-ux so looking for steps to take inorder to implement disaster recovery using ignite.

Thanks.

Check them for what?

Hardware reliability/capability? Use stm (cstm, xstm, etc.) to exercise the various components.

Ability to run your application? You would have to design your own testing for that as none of us have any familiarity with it.

For Ignite disaster recovery, there are basically two ways to go. You can backup to a tape or you can set up an Ignite server and backup over the network. The simplest approach is to use tape and run the following command:

make_tape_recovery -a /dev/rmt/_mn -I -v -x inc_entire=vg00

Recovery is as simple as inserting the tape in the drive and booting from it. It then will interact you much like an install, allowing you to reconfigure your LVM/filesystem layout if you so desire, or just restore as it was. Your other data, which should be in VGs other than vg00, can then be restore from your regular backups.

Shalom Khilari,

Lots of things.

1) Test all application and database software under a heavy load.
2) Do realistic user tests.
3) A complete test plan of all expected functinality.

Here is a thread of mine that deals with this very topic in 2003.

Hi,
to check if on two systems you have same files (same version/update...) you can use

# rdist

(man rdist)

It can tell you if it's ok or also copy newer file from system1 to system2
