One of my cohorts has already seen this.
Here is their response:
We are following up with the track for AIX 5.x.
Refresher: This item was a result of a PMR. After swapping an SSA disk
in rootvg, the new disk is not assignable as a boot disk (via the bootlist
command)
until the system is rebooted. This is due to the fact that AIX builds the
bootable
device tree once during boot and stores the list in NVRAM.
Note that the 'mirrorvg rootvg hdisk_X' command will fail after the new rootvg
disk
is installed because, once again, the disk is not recognized as bootable.

Document Status - Rejected
Title - Rootvg Disks are not Hot Swapable
IBM does not intend to provide a solution to this request for the following
reason:
Reject Reason : Not in Plan
Reject Explanation : No functional enhancements will made to AIX 4.3.3
External Response : AIX 4.3.3 will not be changed to support hot-swapable
rootvg disks.
No functional enhancements will be added to AIX 4.3.3 due to the fact that
AIx 4.3.3 is near end of life (standard service for AIX 4.3.3 will end
12/31/2003).

Subject: Boot off SSA disks
Hi,
I just added 4 more SSA drives to a D40 drawer of which there were
previously 8 drives already.
Bootinfo -B tells me I can boot off the original 8, but not the new 4. That
must say the adapters are OK.
The original 8 are 36g and the new 4 are 18g drives. The new 4 are at mc
level 0023 and 0024 is the latest. So they aren't too far off.
I checked on another system where bootinfo -B once said it could not boot on
SSA, but now says it can. That system has been rebooted after adding the
drives.
Do I need to reboot for some reason so the drives are there at boot time to
mark them as bootable in the ROS?
