I manage a largish number of servers, and I am trying to write a bash script to inspect their BMCs using ipmitool. This is the essence of what I'm doing:
...
admin=$(ipmitool -U user -P pasw -I lanplus -H $ipmi user list | grep " user " | awk '{print $1}')
chn=$(ipmitool -U user -P pasw -I lanplus -H 10.100.10.3 channel info | grep -e '^Channel.*info:' | awk '{print $2}')
ipmitool -U user -P pasw -I lanplus -H $ipmi user priv $admin 4 $chn
ipmitool -U user -P pasw -I lanplus -H $ipmi channel setaccess $chn $admin callin=on ipmi=on link=on privilege=4
ipmitool -U user -P pasw -I lanplus -H $ipmi sol payload enable $chn $admin
ipmitool -U user -P pasw -I lanplus -H $ipmi sol set volatile-bit-rate 115.2 $chn
ipmitool -U user -P pasw -I lanplus -H $ipmi sol set non-volatile-bit-rate 115.2 $chn
ipmitool -U user -P pasw -I lanplus -H $ipmi sol looptest 1
...
It works fine until I reach the sol set ... commands, which fail:
Error setting SOL parameter 'set-in-progress': Attempt to set set-in-progress when not in set-complete state
Error: set of parameter "volatile-bit-rate" failed
Looking at sol set ... from the ipmi shell:
ipmitool -U user -P pasw -I lanplus -H $ipmi shell
I see:
ipmitool> sol set
SOL set usage:
sol set <parameter> <value> [channel] [noguard]
SOL set parameters and values:
set-in-progress set-complete | set-in-progress | commit-write
enabled true | false
force-encryption true | false
force-authentication true | false
privilege-level user | operator | admin | oem
character-accumulate-level <in 5 ms increments>
character-send-threshold N
retry-count N
retry-interval <in 10 ms increments>
non-volatile-bit-rate serial | 9.6 | 19.2 | 38.4 | 57.6 | 115.2
volatile-bit-rate serial | 9.6 | 19.2 | 38.4 | 57.6 | 115.2
So it looks as if one can manually set it to complete - but is it as simple as that? Is there a reference manual for what these commands do?
The following is a description of [Set In Progress] in the IPMI specification.
This parameter is used to indicate when any of the following parameters are being updated, and when the updates are completed. The bit is primarily provided to alert software than some other software or utility is in the process of making changes to the data.
An implementation can also elect to provide a ‘rollback’ feature that uses this information to decide whether to ‘roll back’ to the previous configuration information, or to accept the configuration change.
If used, the roll back shall restore all parameters to their previous state. Otherwise, the change shall take effect when the write occurs.
If your BMC supports this feature, the order of settings is as follows:
ipmitool sol set set-in-progress set-in-progress
ipmitool sol set xxxx
ipmitool sol set set-in-progress commit-write
ipmitool sol set set-in-progress set-complete
