| Description | The node (re)established communication with cluster node machine on network heartbeat. |
| Event Information | According to Microsoft: These same SAN devices can be attached to main frame computers or UNIX operating systems. This can present some challenges because of differences in SCSI commands sets. These anomalies can be caused by firmware revisions or the inability to properly zone or mask the bus resets to control the disks with MSCS Cluster Services. Without this protection in place (and proper masking, zoning or a combination of both) the following problems could occur: 1. Lost delayed write errors of various versions and descriptions. 2. Chkdsk.exe could run. 3. Data loss or damaged databases. 4. Seeing the same disk from both servers. 5. Disk-reservation issues in which the disks are lost temporarily or permanently. |
