moving disks between rx2660 chassis

[dennis cooper]

I want to move a RAID 1 system disk to a different rx2660 chassis. With disks moved, the 'new' Itanium chassis will not boot. What needs to be done to accomplish this?

Same RAID controller used???

You probably need to activate the RAID!

[dennis cooper]

The rx2660 has one 8 slot controller. 'New' disks are not recognized. Does there need to be some disk ID put into controller?

As suggested, the RAID group will need to be activated.  This is done via the EFI shell.  Try this:

Shell> drvcfg -s

This should start the SAS RAID configuration utility.  Go to RAID Properties --> Manage Array --> Activate Array.

Exit out of this and use 'map -r' to refresh your device list.

In EFI shell do

Shell> drivers

and locate the number of the LSI SAS controller, e.g. 23.

then do

Shell> drvcfg -s 23

to start the offline configuration tool.

Most likely you see the RAID deactivated, activate it now.

Thanks. I assume that activating the RAID1 will not force an INIT like the ADD UNIT in the SAS$UTIL??? Then I should be able to boot from the RAID1 disk? Or will I first need to add it to the boot list in EFI??

Good info...thanks.

>will I first need to add it to the boot list in EFI??

in theory rx2660 can have 2X RAID1 mirror, and remains ordinary disks. you first have to activate your new RAID disks according to slots, for example first 4 disks, as recommended here,  and you have to reinstall your OS , during installation phase installation warns you to make efi partition during FS setup vfat like /boot/efi    .
