Ways of getting partition consoles NOTE1: Better use putty instead of command prompt...as command prompt mimic the character twice for some unknown reasons. NOTE2: I usually open partition consoles through vnc sessions raher than any putty session 1. Reaching Partition console using 30002 session      This can be done only if fsp is in runtime (smsgr mfgState  command should  display runtime ) and the fsp is primary fsp.      a. go to asm (https:// ) network services -> debug vtty -> you will see 3 text boxes partition id sessiosn id and timeout.           Enter the partition id ( you can get this id either from phyp or from hmc)..in case of blades.....we usually have one partition...so we always use '1' for blades           Enter the session id as '0' ( this should always be zero   for partition consoles ...'1' is for getting partition firmware oflite sesisons...which is only used for pfw debug purpose )           Enter the timeout as you wish
