Removal and replacement procedures 65
•
Board insertions do not convert the AMP mode while the server is running.
A server cannot be converted from Advanced ECC to another AMP mode by
inserting a board while the server is running. Board insertions in Advanced
ECC are solely for making additional memory resources available to the
operating system.
•
Advanced ECC is the only mode in which hot-add operations are supported,
and is the only mode in which the amount of memory available to the
operating system can be increased without a reboot.
•
If a memory board (which contains DIMMs) is unlocked while in Advanced
ECC mode, audio alarms and visual alerts occur.
The following rules apply to hot-add operations. Hot-add is performed by adding
a memory board while the server is running, and the additional memory is made
available to the operating system without a reboot.
•
Boards must be inserted sequentially.
•
Multiple hot-add board insertions can be performed one at a time on the
same server. For example, if a server has three empty memory board slots,
three hot-add board insertions can be performed.
•
If multiple hot-add operations are performed, allow one board insertion
operation to complete (as indicated by the memory board LEDs ("Memory
board components and LEDs" on page
94 ) and operating system logs) before
inserting another memory board.
CAUTION: When the memory board locking switch is unlocked in
a mode that does not support hot-add or hot-replace capabilities, audio
alarms and visual alerts occur. Removing the memory board at this
point causes server failure.
To end the audio alarms and visual alerts, move the memory board
locking switch back to the locked position. This action does not result in
data corruption or server failure.
If removal of a single memory board is required and it is the only
memory board, power down the server and make the necessary
memory changes.
