Unit "VOLUME FAILED": How to deal with this error on MSA1500cs?

[stephen peng]

Guys,

I could only access the MSA1500cs by serial cable, and show unit told:

Unit 0:
In PDLA mode, Unit 0 is Lun 1; In VSA mode, Unit 0 is Lun 0.
Unit Identifier   :
Device Identifier : 600508B3-009058B0-A6645ABD-420A0001

Logical Volume Raid Level: DISTRIBUTED PARITY FAULT TOLERANCE (Raid 5)

What is the problem? would that mean a data lost? can I fix it? if not, how to recreate a new lun  through my current access mode.
