Standby controller MSA 1500

[andy steven]

on the 1000/1500 controllers do the standby controllers present the LUNs while the active controller is working?

i have 2 hbas in the server and 2 i/o fibre modules and 2 controllers.

I have software zoning on the switches with the 1 HBA to each of the controller i/o modules.

Curently i only see the presented disk once. In SSP both HBAs have access to the LUN, one is showing as online the other is showing as off line... is this correct??

Andy:

The standby controller supposedly presents the LUN, but it is not accessible.

Are you running Secure Path on the host? or the MPIO driver?

It's been a while since I worked on a MSA, but I think that the connection should say "online". Check your zoning and check the WWID it is reporting with the actual WWID of the hba in the server.

Is this a new MSA install?

Hi,

last time I looked on an MSA, the 2nd (inactive) HBA showed up in the SSP list as "Offline". That was normal.
If you're running SecurePath, run the spmgr display command to see what paths are available.

thanks guys. i have done some testing and the standby controller does present the LUN but you can not write to it. Got MPIO working like a dream on it now.

many thanks
