IR on rx6600

Pravin Salgaonkar — Wed, 17 Feb 2010 11:30:10 GMT

Hi All,

We have an rx6600 with IR configured.Now We want to apply the latest 11.31 patches on the server. we would be taking an ignite backup prior to patching.Just want to check the possibility that can we break the IR and boot from one of the internal disk and apply the patches. If we are not good with the patching then can we boot with the mirrored disk. Also after patching if things go fine can we sync the mirror disk back.
We dont have any problem with downtime i.e multiple reboots are OK with us.

Thanks In Advance.

By Consider above as you said.

simple & hassle free & easy :-

You go for Ignite backup " Once Ignite backup has been completed,

Patch the server

if got some issue :-

Recovery Entire Server / Using ignite backup

Yes. Its possible, but too many steps to do.
if you have the Ignite backup, I personal recommend to go for recover the server by "Ignite backup"

Hi Johnson,

Thanks for your reply. I am not talking about OS mirror using Mirror UX. I want to break the harware mirror on rx6600.
I am aware of the Ignite backup still wanted to know the possibility of breaking the IR and doing it.

Thanks

well..
if its Hardware Raid disk. easy also

step 1:-

# make_tape_recovery (or) make_net-recovery

# shutdown -hy 0

unplug "2 -Disk's are hot swappable" -> Hence its hardware Raid. keep it safe

boot the system .

Patch the System.

if everything goes well

put back "2 disk" -> disk will "Sync back automatically"

(HW Raid "Doesn't look "Pri-disk" / Sec disk" Once disk plugged-in it will automatically start rebuilt) that concepts of having "HW" raid -> as for as i know.

And i have done this things "HP Proliant DL 385" Servers

HTH,
Regards,
Johnson

Ok then what if we want to revert back to the old setup. how can we boot from the disk we have removed...rather how can we sync the removed disk to the one in the server

I would recommand ignite or DRD.

Maybe DRD is best for this, because you can patch the clone and boot later.

However, if you want to boot from the removed RAID member, shutdown, remove the other disk, insert the disk you removed first and boot.

Maybe you need to go to the controller BIOS and enable the IR.
