invscout (general) diagnostics

------------------------
Source File Name: GetFwLev.c

Source File Revision: $

Error Code: 10200

Error Text:

No data in stdout of shell command

------------------------

Cause

This issue could be cause by the old_rootvg.

Environment

All AIX environment.

Diagnosing The Problem

Collect the truss output for the invscout command and verify the /usr/sbin/lsmcode command. If it is trying to display microcode level information for old_rootvg then that's the issue.

Resolving The Problem

To solve the issue, you need to run "alt_rootvg_op -X old_rootvg" to remove the entry for old_rootvg from the ODM. It will not destroy the old_rootvg disk so that you can set bootlist to the old_rootvg disk and reboot from it if necessary.
