My raid went down during a power surge after it overloaded my UPS. I powered it up and noticed it changed my IP addresses on my MDC and my client, leaving me unable to mount the volume and connect properly to the Xsan.

I decided to change my IP addresses to make them static instead of dhcp so that wouldn't happen again. So I added a SAN with the proper address and removed the old one.

Now I can't see the MDC, Client, and the Luns.

I ran a cvfsck and it says the server can't find any Meta-data devices.
What should I do from here and does removing a SAN delete files on the volume?

    Can you change things back to the DHCP assigned IP addresses? In other words, do you know the addresses that were previously assigned so you can manually put them in? If your DHCP pool is locked somehow, you can create DHCP reservations on the server.

    I think that's the easiest thing to do...

    Check this file:

    /Library/Filesystems/Xsan/config/SanVolume.cfg

    Does the content from this file contain your old setup?

    When it does, you have a good change to restore you data, when it doesn't forget it, your data if gone...

    When it does, restore the old IP addresses for clients and hosts

    Afterwards start using the CLI, do not use the GUI app.

    You have to use: cvadmin

    SystemStarter start acfs
    cvadmin shows your Xsan volume?

    When it doesn't: type activate 'XsanVolume' followed by start 'XsanVolume' replace XsanVolume with your own XsanVolumename...

    Goodluck!
