You said you tested it with a windows server, so you must have defined that second host and mapped it to the volume.
I guess you can remove the mapping from some V3700 menu.
Sorry, I've run out of ideas - the only thing I can suggest is to create a partition, format and mount it, and then test it.

I commented, I could already set the multipath route I attached a photo, as you can see I have the "8 disk" mapped in one, I guess I have to use the mapped disk as you can see, but when it comes to mounting it I get that this superblock, as I read I have to create the file system I have in this case the ext4 but when I run the command mkfs.ext4 the server hangs up and I reboot all the processes I do not know if something else I need to do?

How did you create the partition, and what's the output of: fdisk -l /dev/mapper/mpathd
Don't think it will make any difference; could you try XFS instead of ext4?
I don't think this will work either, but it may be worth a try:
- shut down the server
- disconnect the FC cables
- start the server and check if all is well
- shut down the server
- reconnect the FC cables
- start the server and see if you lost the six of the eight disks

BTW: there's no image.

fdisk -l /dev/mapper/

Hi, tunk,

I attached the details, in addition to that to see if more then I do those steps I tell you that when I restarted all the processes trying to give the ext4 file system to the partition / dev / mapper / I was alarmed by the server with an error in the PCI but I think it was the same error that tried to force the file system.
