The software product SIR (System Install and Restore) is used to install a pubset during system installation or in ongoing operation.
In addition, SIR offers facilities for initializing disks (VOLIN utility routine).
The SIR utility routine allows you to install home pubsets for operation under the current version of the BS2000 operating system (target version), and to create an IPL disk for the current BS2000 version (target version) which can be used from various execution versions of BS2000. The following applies here: execution version <= target version. Normally the two predecessor versions of the target version are supported as the execution version.
In BS2000 OSD/BC V11.0, a version changeover on the server units /390 and x86 can be based on the execution versions BS2000/OSD-BC V10.0 or V9.0.
In general, each SIR version is linked to a particular BS2000 version. This means that SIR can only generate BS2000 systems of the currently used or of a newer BS2000 target version.
It is recommended to keep a suitable home pubset or IPL disk, in case you might need to return to an earlier version in the future.
You should bear in mind that only device types belonging to the device spectrum of BS2000 (both in the execution version and in the target version) are supported.
For a detailed description of the SIR utility routine see the “Utility Routines” manual [1].
