Hi,
we have currently (big?) problems after our SAN went down due the disk fail. Now the SAN is again fully up and running after complete rebuilding of its RAID. Problem is that now our ESX servers can see only two out of six LUNs (vml.0200020000600805f3001a0350a10cb7ca973d00044d5341313030 and vml.0200060000600805f3001a0350ace30859127200084d5341313030).
When starting to add new storages, the servers can see also rest of the LUNs and VMFS file systems on mentioned LUNs. Problems is that we don't want to add those again since reformatting happens and that would mean data loss.
Below is a listing of vmfs disks from two of our ESX servers.
Any idea why other server sees some mystical disks (see bolded lines)? Any idea how to fix this?
