We have a HP MSA2012i SAN it was mapped to our backup server via ISCSI and appeared as 4 drives G,J,K and L. Since Tuesday morning the drives have disappeared from the server. I have had a look at the SAN and cant see any problems which are obvious with it. In the backup server logs there were some iscsiPrt error logs see below
Connection to the target was lost. The initiator will attempt to retry the connection.
The initiator could not send an iSCSI PDU. Error status is given in the dump data.
Initiator failed to connect to the target. Target IP address and TCP Port number are given in dump data.
An help would be greatly appreciated?
