Tivoli Storage Manager for Windows: Administrator's Guide
As part of your regular routine, check the event log to ensure that the
configuration is operating properly. If a server fails, it will be
logged. The log provides you with some idea as to why the failure took
place.
Sometimes a node must re-join the cluster, for example:
- Node failed
- Equipment changed, such as a new SCSI card added
Do the following (in any order) to ensure a successful entry into the
cluster:
- Ensure that the SCSI bus resets are disabled before bringing the failed
node back online.
- Terminate the shared SCSI bus. It is possible that the bus could be
in less than an ideal condition and the signal at the bus would not be
optimal.
- Update, if necessary, the drive and library using the TSM Cluster
tool.
- Ensure that only tape devices are connected to the shared bus.
Devices such as CD-ROM drives or removable media devices, should not be used
on the shared bus. Doing so could result in a failed operation.
- Take the TSM server offline until the failed node has re-joined the
cluster. This avoids the possibility of impacting the TSM server
running on the other node.
