We have dss with 40 tb iscsi target unit working under lsi raid controller.
After a proper restart system started to give error : no system volume found..services can work without....We cant get the data. I read some post on the forum about the same error. I used c-A-x extended tools . Default volume group is checked vg00. There is no other vg on the system.(as it should be) So i tried to restore lvm config option on the menu. There are 6 restore points. first 3 of them shows vg00 (after the error) But last 3 shows vg01... How can i get my data back. Do i have to rename vg00 to vg01 back? and how can do that?

PS:Sorry for my bad english...
