Solution 2362113.1 : VSM6 - IDR1626.1 Installation (can induce panic in VSM7)

Applies to:

StorageTek Virtual Storage Manager System 6 (VSM6) - Version All Versions and later
StorageTek Virtual Storage Manager System 7 (VSM7) - Version 7.0.0 to 7.1.2 [Release 7.0]
Information in this document applies to any platform.

Symptoms

VSM6 or VSM7 panic during the installation of IDR1626.1 on another VSM6 connected to the same FICON infrastructure.

Changes

IDR1626.1 is being installed on a VSM6.

Cause

There is a point in the VSM6 installation of IDR1626.1 where the machine does not know it is a VSM6.
During that time frame the VSM6 can generate unexpected RNID ELS events. (RNID ELS = Request Node ID Extended Link Services)
If the FICON infrastructure is common to another VSM6 or VSM7 these RNID ELS events can cause the receiving machine to take a panic.

Solution

Workaround:

Completely isolate the VSM6 being upgraded with IDR1626.1 from the FICON infrastructure.
This can be done by blocking the switch ports going to the VSM6 being upgraded or by unplugging the FICON cables going to that machine.

Fix:

This problem is addressed in version 7.1.2.05.000 and higher levels of VSM6 and VSM7 code.
