dacNONE error: dac1 missing from ds4800 router.

[J1gh2]

I have just realised that my lpar can only see through one path to the storage server.

fget_config –A shows:

---dar0---

dac0 ACTIVE dacNONE ACTIVE
hdisk2 dacNONE
hdisk3 dac0
hdisk4 dacNONE
hdisk5 dac0
hdisk6 dacNONE
hdisk7 dac0
hdisk8 dacNONE
hdisk9 dac0

I have run rmdev –Rdl dar0, fcs0, fcs1, dac0 and checked the host port information on the storage server is the same network address returned by lscfg –vl fc0 and fcs1. I then run cfgmgr again but I still get the above.

This is the sixth lpar on the frame and lslpp -l | grep devices.fcp* shows that the firmware level is the same as the other lpars (running aix 5.3) but I do not have this problem with any other lpar.

Any ideas please?

Thanks

you can check the config of san switch,specially the zone config.

Thanks chinaix,

This has been resolved but yes, you are right. The zone config had changed so I restored from backup and this issue went away.

Thank you very much
