User created filesystems on VIOS
Can i create an additional filesystem on a VIOS ? I want to run nmon and want a location to store the output files ? Would it be better practice to just create an nmon directory under /home/padmin ? Can anyone tell me what the IBM directive or recommendation on this is. Thanks. -
