NIM 서버에서 Non-rootvg Backup

1. 고려사항

• 이 문서는 기존에 NIM Server / Client 구성이 되어있다는 가정하에 작성된 문서입니다.
• NIM Master에 백업하고자하는 Client의 Machine 등록 및 네트워크 통신이 정상적인 상태라는 가정.

2. NIM 서버를 이용한 Non-rootvg 백업 - SMIT

• NIM Machine 등록확인 및 상태체크

[NIM_Master:root] /export/lpar10] lsnim -l lpar10
lpar10:
   class           = machines
   type            = standalone
   installed_image = 71_mksysb
   current_master  = NIM_Master
   connect         = shell
   sync_required   = yes
   platform        = chrp
   netboot_kernel  = 64
   if1             = net-pri lpar10 0
   cable_type1     = tp
   Cstate          = ready for a NIM operation
   prev_state      = not running
   Mstate          = currently running
   cpuid           = 00C48B554C00
   Cstate_result   = success

          º Cstate 는 NIM Client의 상태를 나타내며, 현재 상태는 "ready 상태"이므로, 바로, Backup이 가능하다.
