I've successfully transplanted an IBM xSeries drive to a P520:
Source drive was a 146G FRU 39R7342.
AIX sees it as:
I had an extra 520 sitting about with no drives. It was going in the junk heap so I thought 'why not'. Don't recall how long I ran it, but it was non-productive use. I recall getting AIX to install was a bit of a problem. I swapped in a good Power drive that we yet to have crushed to run AIX from, then I could create a vg/lv/fs on the transplanted drive. I would not TRUST any data on it, but know that it is possible! What you will want to watch out for is the SAS type, the P520 using 3g SAS, but if you have an IO drawer its not uncommon to have SCSI drives for the expansion. Page 15 of the redbook Neo posted above have the feature codes (yes, I still have some p520's in productive use) that are authorized.
I no longer have that system running and it went to the recycle some years ago. I was excited at the time I had to email my other AIX team member for the 'check this out' factor. That's how I know all the gory details of the transplant! Oh, this was in a 8203 frame by the way.

mlxctl
MLXCTL(8) BSD System Manager's Manual MLXCTL(8)NAME
mlxctl -- Mylex DAC960 family management utility
SYNOPSIS
mlxctl [-f dev] [-v] [-a] status [drive] [...]
mlxctl [-f dev] [-a] detach [drive] [...]
mlxctl [-f dev] [-a] check [drive] [...]
mlxctl [-f dev] rebuild channel:target
mlxctl [-f dev] cstatus
mlxctl [-f dev] rescan
mlxctl [-f dev] config
DESCRIPTION
The mlxctl utility performs status monitoring and management functions for Mylex DAC960 RAID controllers and attached devices.
The following options are available:
-a Apply the action to all drives attached to the controller.
-f dev Specify the control device to use. The default is /dev/mlx0.
-v Increased verbosity.
The following commands are available:
cstatus Display the controller's current status.
status Display the status of the specified drives. This command returns 0 if all drives tested are online, 1 if one or more drives are
critical and 2 if one or more are offline.
rescan Re-scan the logical drive table, and attach or detach devices from the system as necessary.
detach Detach the specified drives. Drives must be unmounted and unopened for this command to succeed.
check Initiate a consistency check and repair pass on a drive that provides redundancy (e.g., RAID1 or RAID5). This command returns imme-
diately. The status command can be used to monitor the progress of the check.
rebuild Rebuild onto the specified physical drive. Note that there can be only one running rebuild operation per controller at any given
time. This command returns immediately. The cstatus command can be used to monitor the progress of the rebuild.
config Write the current system drive configuration to stdout.
EXAMPLES
Display the status of drive ld3 attached to the controller mlx1:
mlxctl -f /dev/mlx1 -v status ld3
SEE ALSO ld(4), mlx(4)HISTORY
The mlxctl command first appeared in NetBSD 1.5.3, and was based on the mlxcontrol utility found in FreeBSD.
