i am having the following problem:
we have an HP-UX clustered system consisting of 2 rp3440 servers with an EVA 3000.
The fact is that morning the system showed malfunctions and the disks on the bays could not be detected: #ioscan -fnC disk only shows internal disks directly connected to the server.
Any help is much appreciated.
Regards
Solved! Go to Solution.

Re: problem with EVA/Cluster
apparently the management server which manages the EVA 3000 (HSV 100) is showing problems. Could that be the reason for the cluster showing malfunctions and the nodes not detecting the disks on the bay ??
how should i proceed in that case?
Thanks in advance

Re: problem with EVA/Cluster
And what's the status of your FC connection from the server to the EVA array?
#fcmsutil /dev/fc....
What's the topology of your SAN? switched fabric, point-to-point? You should also check the status of your san-switches, if they are being used.
But first give me the fcmsutil /dev/fc... output.
Do you have any person responsible directly for storage? Might need to check with storage/SAN team....

Re: problem with EVA/Cluster
Check the Hardware status of the EVA3000 through management Serer Command View EVA. Is there any warnings on the Hardware lists? Is there any warnings on the VDISKs section? Is there any amber warning LEDs on controler / disks?
Thanks

Re: problem with EVA/Cluster
Topology = PTTOPT_FABRIC
Link Speed = 4Gb
So you should check your fc switch/zonning/storage , for possible problems.
Once they are fixed, re-scan with ioscan again

Re: problem with EVA/Cluster
That was an example from my system. It was just to demonstrate how to get the output from his server :) .He still didn't provide his output...
