Hi,
How to break the mirror and enable again.
my use case is as given below
1. i have a HP Gen 9 BL460c server blade with two SAS disks. Two disks are configured for RAID 1
2. I want to update host operatin system configuration. Before starting configuration changes, i want to disable/break the mirror so that if enything goes wrong wrt to my configuration changes on host operating system, I can revert to old setting by restoring from RAID mirroring
I am looking for online mode procedure.
i have hpssacli tool installed on the node.
Please provide steps/hpssacli commands that can be executed from hostoperating system to enable/disable RAID 1 mirroring.
Thanks and regards,
Adishesh

Re: RAID 1 breaking mirrors and rebuilding drives
Even if you break the mirror you need to remove the disk - so there is no real online method.
Better shutdown, remove a disk and boot again. If something go wrong, shutdown, insert the backup disk only and boot up.
Hope this helps!
Regards
Torsten.

SolutionHi Torsten,
Thanks for the reply.
With HP Smart array controller i was expecting simple steps to disble/enable mirror.
in my use case i can not performe disk removal activity as HP blades are located remotely and i have only ssh access to blades.
Thanks and regards,
Adishesh
