1. Find IMM version using dmidecode in Linux
dmidecode|awk -F\- ‘/Integrated Management Module/ { gsub(/\[|]/,””);print $2 }’
2. Upgrade the IMM firmware version
download the .bin file example yuooe3c version upgrade file name “ibm_fw_imm_yuooe3c-1.33_linux_32-64.bin” and execute as root login using -s option
./ibm_fw_imm_yuooe3c-1.33_linux_32-64.bin -s
Note: This will not reboot the server automatically. New version can be identified through dmidecode only after reboot
3. use asu64 utility to mange IMM from command mode.
Usage: ./asu [apps] <cmds> [<cmd_mod> | <class>] [<options>] [<connect_opts>]
Commands:
–license rebootimm
batch rebootbmc
comparedefault rebootrsa
delete replicate
deletecert resetrsa
dump restore
encrypt save
export set
generate setenc
help show
import showdefault
loaddefault showgroups
nodes showlocation
patchadd showvalues
patchextract version
patchlist readraw
patchremove writeraw
rebootimm
4. To check values, first dump all values to a temp file and use the file for reference
/opt/ibm/toolscenter/asu/asu64 show all 2>/dev/null >/tmp/imm-dump.txt
grep IMM.NTPHost /tmp/imm-dump.txt
IMM.NTPHost=nn.nn.nn.nn
5. To modify individual property value:
/opt/ibm/toolscenter/asu/asu64 set IMM.NTPHost <IP address>
6. To Modify multiple values, then create a temp file /tmp/imm-values.txt with values
set IMM.DNS_IP_Address1 “nn.nn.nn.nn”
set IMM.DNS_IP_Address2 “nn.nn.nn.nn”
set IMM.NTPHost “nn.nn.nn.nn”
set IMM.SMTP_ServerName “nn.nn.nn.nn”
then input the temp file /tmp/imm-values.txt to asu64 tool
asu64 batch /tmp/imm-values.txt
As some values will reflect after imm reboot, reboot it using rebootimm
asu64 rebootimm
