Hi, there,
a customer of our's, running three ESXi 5.1 hosts connecting to two HP storage systems via iSCSI, had some planned downtime this weekend.
Upon bringing back up storage and Servers, they found the had no access to the VMFS volumes.
The LUNs can bee seen via the devices tab all right - but they cannot be seen as datastores.If I connect manually, I am only asked to initialise the LUN.
One thing I noticed: In the vmkernel.log, I have lines stating that devices could not be mounted by any fs driver which sounds like a bad thing for me..
Any thoughts what could cause the trouble here? As far as I know no configuration changes have been made, the stuff has been running nicely for months. I am at a loss....
Thanks in advance
Dirk
