HMC command line [draft]

lshwres – opcje HEA

chhwres -  changes the hardware resource configuration of the managed system (DLPAR)

chsyscfg – changes the attributes of partitions, partition profiles, or
system profiles for the managed system

rsthwres – restores the hardware resource configuration of
partitions in the managed system. This operation might need to be performed
after a DLPAR operation fails

for the managed system

lssyscfg – lists the attributes of partitions, partition profiles, or
system profiles for the managed system.

lslparutil – lists utilization data that is collected for a managed
system

[def | ls | rm ] sysplanres – defines, show, delete a system plan resource for use by system plans deployed from the HMC

dump – sets the system dump parameters for the managed system

[ch | ls ] cod – performs CoD operations on the managed system

mksysplan -

chsvcevent -

chhmc – set the date, time, time zone, and clock on the HMC
