However, DIMM capacities can be different between different DIMM pairs. For
example, a valid mixed DIMM configuration may have 1GB DIMMs installed in
DIMM Slots A0/B0, and 2GB DIMMs installed in DIMM slots C0/D0.
DIMMS should be installed with the largest module pair size first. For example, (4)
4GB DIMMs and (4) 2GB DIMMS should be installed as follows: A0/B0=4G,
C0/D0=4G, A1/B1=2G, C1/D1=2G
Scripting the SP/BIOS Flash Process
The SP/BIOS flash process includes an “Update Successful” message when the
service processor (SP) flash finishes. This message signals the end of the SP flash
activity
only
. At this point in the process, the BIOS has
not
been flashed and
premature termination of the process (for example, a manual reboot) will result in
BIOS corruption. To avoid corrupting the BIOS review the flash sequence below:
Note –
Before writing a script to flash the BIOS/SP remotely, observe the sequence
in real-time and test the script on a single system before updating all systems.
1. SP begins the flash process.
2. SP completes the flash process.
3. CLI returns an Update Successful message.
4. The system reboots and the BIOS begins the flash process.
5. The BIOS flash process finishes.
