   Controller Status: OK
   Cache Status: OK
   Battery/Capacitor Status: OK

2. Show configuration of all RAID controllers: 
#:hpacucli ctrl all show config

Smart Array P400 in Slot 0 (Embedded)

   array A (SAS, Unused Space: 0 MB)


      logicaldrive 1 (68.3 GB, RAID 1, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 72 GB, OK)
      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 72 GB, OK)

   array B (SAS, Unused Space: 0 MB)


      logicaldrive 2 (68.3 GB, RAID 1, OK)

      physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 72 GB, OK)
      physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 72 GB, OK)

#:hpacucli ctrl slot=0 show config

Smart Array P400 in Slot 0 (Embedded)

   array A (SAS, Unused Space: 0 MB)


      logicaldrive 1 (68.3 GB, RAID 1, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 72 GB, OK)
      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 72 GB, OK)

   array B (SAS, Unused Space: 0 MB)


      logicaldrive 2 (68.3 GB, RAID 1, OK)

      physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 72 GB, OK)
      physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 72 GB, OK)











In case that any of components fails status of RAID controller will change

#hpacucli ctrl all show status

Smart Array P400 in Slot 0
   Controller Status: OK
   Cache Status: Temporarily Disabled
   Battery/Capacitor Status: Failed (Replace Batteries/Capacitors)







Without hpacucli this failed battery failure is show when you reboot server and looking at screen or(probably) when you connect on iLo and check health status of server.
