IBM 3590 - Manual (Page 132)

You can select, depending on your software, the severities you wish to see.
For example, you may only want to see the acute SIM/MIM, or prefer to see
all SIMs and MIMs sent to the host. SIM/MIM filtering by severity can be
done through configuration options. The four severity codes are listed below:
v Severity 0 (FID4) code means the device requires service, but normal drive
function is not affected.
v Severity 1 (FID3) code means the problem is moderate.
v Severity 2 (FID2) code means the problem is serious.
v Severity 3 (FID1) code means the problem is acute.
A MIM specifies what is wrong with the cartridge that is indicated. The three
MIM severity codes are listed below:
v Severity 1 indicates high temporary read/write errors were detected (moderate
severity).
v Severity 2 indicates permanent read/write errors were detected (serious
severity).
v Severity 3 indicates tape directory errors were detected (acute severity).
SIMs and MIMs can be reported multiple times. A configuration option allows
reporting the same SIM/MIM more than once. The time between repeat
SIMs/MIMs is eight hours. For example, if the configuration option is set to
two, a SIM will be reported when an error occurs, it will be repeated again
eight hours later, and, then again, eight hours after that message. The default
is to not repeat SIMs/MIMs.
SIM/MIM Presentation
SIMs and MIMs reporting varies for different systems. Refer to the Statistical
Analysis and Reporting System User Guide which can be accessed on the IBM
URL, http://www.storage.ibm.com/hardsoft/tape/pubs/pubs3590.html. This
is not an orderable book.
There are specific SIM and MIM presentations for the following systems-
