Note on the iSM server are described below.
1. One iSM server can be installed/operated in one server.
2. One disk array should be controlled by one iSM server.
3. If installing multiple disk arrays or installing an additional one, you need not run or add multiple
iSM servers.
A single iSM server can monitor multiple disk arrays.
Note the following about iSM versions:
• If you have multiple iSM media, use an iSM server of the latest version.
The reason for this is that iSM servers of older versions do not support new disk arrays.
• If you install a disk array of a new type, you need to upgrade the currently running iSM server
to the latest version.
• iSM clients must use programs of the same versions as those on the servers.
4. To conduct monitoring from multiple iSM servers at the same time, install a single iSM server for
monitoring a disk array and connect multiple iSM clients to it for monitoring.
The reason for this is that a disk array cannot be monitored by multiple iSM servers at the same
time.
If configuring iSM servers into a cluster, configure them into a unidirectional standby cluster so
that they are monitored by a single server at the same time.
5. When there are many resources of a disk array, the amount of information to be collected is
increased. Therefore, it may take a few minutes until the iSM server starts and the monitoring
of the disk arrays resumes.
6. The contents of mail header file are sent in sequence to SMTP server in the mail function at the event link.
However, in case that a part of Windows base SMTP server does not accept starting a new
paragraph without using <CR+LF>, should be modified to <LF> to <CR+LF> by altering it to
start a new paragraph in the mail header file.
7. iSM server stops the mail transmission service after any problem occurs when communicating with the
SMTP server.
In resuming, please re-start iSM server.
The mail transmission service may be blocked by activation order, especially when the SMTP
server is operated simultaneously in the same machine.
8. If iSM server cooperates with SNMP trap service, and SNMP trap service is re-started while
running, SNMP trap cannot be received after restarting. In this case, re-starting of iSM server is
needed.
