How to find out WWPN for NetApp Storage

Filed under: NetApp — Akther @ 7:19 pm

We have bought a new FAS 2050 dual controller storage box. Just want to see the WWPN information of the two fiber channel cards in NetAp. Below two commands are helpfull to see these information

 FAS2050A> sysconfig -v

        slot 0: Fibre Channel Target Host Adapter 0b
                (Dual-channel, QLogic 2432(2462) rev. 2, 64-bit, <OFFLINED BY USER/SYSTEM>)
                Firmware rev:     4.5.2
                Host Port Addr:   000000
                Cacheline size:   16
                SRAM parity:      Yes
                FC Nodename:      50:0a:09:80:88:5d:49:b0 (500a0980885d49b0)
                FC Portname:      50:0a:09:81:98:5d:49:b0 (500a0981985d49b0)
                Connection:       No link

FAS2050A> fcp show adapter
Slot:                    0b
Description:             Fibre Channel Target Adapter 0b (Dual-channel, QLogic 2432 (2462) rev. 2)
Adapter Type:         Local
Status:                         OFFLINED BY USER/SYSTEM
FC Nodename:          50:0a:09:80:88:5d:49:b0 (500a0980885d49b0)
FC Portname:            50:0a:09:81:98:5d:49:b0 (500a0981985d49b0)
Standby:                 No

I was thinking why it’s showing  OFFLINED BY USER/SYSTEM.  Then i checked the filer view and it was showing interface is down

Then i tried to up the adapter and this was the issue actually. FCP  was not started.

FAS2050A> fcp status
FCP service is not running.

FAS2050A> fcp start
Mon Jul 25 19:01:41 AST [FAS2050A: fcp.service.startup:info]: FCP service startup
Mon Jul 25 19:01:41 AST [FAS2050A: scsitarget.ispfct.onlining:notice]: Onlining Fibre Channel target adapter 0b.
Mon Jul 25 19:01:41 AST [FAS2050A: scsitarget.ispfct.initFailed:CRITICAL]: Initialization of adapter failed on Fibre Channel target adapter 0b.

Then connect the cable in to 0b port and SAN Switch. Now everything looks fine

FAS2050A> fcp show adapter
Slot:                    0b
Description:             Fibre Channel Target Adapter 0b (Dual-channel, QLogic 2432 (2462) rev. 2)

FC Nodename:             50:0a:09:80:88:5d:49:b0 (500a0980885d49b0)
FC Portname:             50:0a:09:81:98:5d:49:b0 (500a0981985d49b0)
Standby:                 No
