I have got an IBM SAN StorWize V3700 which is having the following issues after a power cut:

1. I cannot ping the IP

2. No activity on the disks

3. My servers cannot see the LUNs

I tried the following but nothing worked:

1. Reboot the SAN

2. Ping the default IP - no response

3. Insert FAT32 pen drive with satask.txt - no files created

There seems to be no response at all from the SAN.

Thanks for your support.

A V3700 has more than one IP - have you tried pinging them all? You've got the floating management IP but then each head should have it's own IP.

How long did you leave the USB stick in the SAN for? 

Is this device under active support with IBM?

Do the disks spin up at all? 

This sounds like hardware failure. Is there a service contract on this device?

Unfortunately No Support contract with IBM. I have tried pinging the second IP but still no reply

Disks do not spin up. No activity at all.

It's Dead Jim.

Sounds like it could be "just" the power supply. Do you have a friendly hardware guy who can check?

It could also be a fried backplane/motherboard on the device. In which case, you may be able to move your disks to a new server.  But doing so incorrectly CAN result in total data loss. The disks could, of course, be restored by a 3rd party company like OnTrack. (I have receipts for both).

Sorry if that is not what you wanted to hear!

A 3700 has a PSU in each head. If one was down, the other would take the load. However, a check of both power cables, the plugs, etc is a good idea as, at a minimum, there should be some activity of the lights on the power supplies at least.
