How do I recover data from corrupt LUN on EMC Clariion CX-320
Posted on 2010-01-13
We have had several problems over the past couple of days with our EMC Clariion CX3-20 SAN. The initial errors seem to point to one of the ports on one of the SP's. In Powerpath there is a red cross on SP A1 and it shows everything as Status Failed State Dead. With each SP being dual port i didnt think this would cause a major problem. Since the errors we have 2 LUN's that all of the data look as though it has been formatted? The LUN's are part of a Storage group that link to 2 File Servers. All of the The LUN's show up in the Disk Management for both servers but the 2 in question show as Online but Unallocated for both. The others depending on which server controls them show Online/Healthy or Unreadable/Unallocated because they are being controlled by the other server.
Do you know if there is anyway of recovering the data from the 2 LUN's showing as Online\Unallocated or a way of making them accessible again as the only option you have is to make a new partitiion?
