Create RAID 1 on RX6600

[Torsten.]

Looks like disk6 and disk9 are your boot disks. In your first attempt you worked with disk6, now with disk9.



>>
WARNING: Make sure that the disks are not being
used for BOOT, SWAP, DUMP, LVM, VxVM or any other
purpose.

This operation will overwrite the data on the disks.

Hi

Torsten is right.
if you do from sasmgr, you lose OS.
if you do from mirror-ux (lvextend -m1 ....) you can do online and you dont lose anything.

Hi Torsten,

why it will be gone ?? HP installed the OS on disk on bay number 8 and I'm putting this as my first disk in the command.

[Torsten.]

The command is telling you:

This operation will overwrite the data on the disks.


Reason is, the hardware raid will use the very last block on the disk, where currently the backup partition table is. Loosing the partition table means loosing the disk contents.



You will loose all data on the disk.

Okay guys, thanks a lot. but to make sure if I get it:

This command :
sasmgr add -D /dev/sasd1 -q raid -q level=1 -q enc_bay=1:8,1:7 -q size=286080

will overwrite the disk on bay 8 with the data on bay 7 witch mean I'm going to loos my OS.

As I told you the OS is on disk bay 8 and disk 7 is empty blank disk.

Thanks

[Torsten.]

No. It will just delete the data on both disks and create an *empty* mirrored disk.

Oh God, so at the end I have only MirrorDisk left to do it + DRD for disaster

[Torsten.]

I would do one of the following:

1) backup with ignite, create the RAID, restore the image

2) create a DRD clone, create the RAID, boot the clone and LVM mirror the clone to the RAID, boot from RAID

3) create the RAID, LVM mirror the current boot disk to the RAID, unmirror from the non-RAID disk

Thanks a lot
