Command "ps" shows that "luxadm insert_device" hangs with child process "drvconfig -i ssd".
Power cycle the A5200, reboot E6500 server with "-r" option, server failed to boot up.

Resolution
The symptoms match that described in:
Sun Alert 228522
According to the Sun Alert, the resolution is to upgrade KJP to 105181-34 or later.

Relief/Workaround
In our case, we followed the workaround according to Sun Alert 48586, booted the server without "-r" option, added the following entry to the /etc/system file:

set kobj_map_space_len=0x200000

then rebooted the server with "-r" option, the problem solved, we then finished the disk drive replacement procedure.

Comment: This appears to be technically correct, but I'm wondering if it is necessary since the contents are already covered by the SunAlert.
