Boundary Condition Can Occur Causing Container Files in a Directory-Container Storage Pool to be Deleted (IT26003)

Flashes (Alerts)


Abstract

Under certain conditions, it is possible directory-container file pointers might be inadvertently removed from the IBM Spectrum Protect Server database.

Content

Problem Summary:

Under certain conditions, it is possible directory-container file pointers might be inadvertently removed from the IBM Spectrum Protect Server database. This is usually triggered by an extremely slow, or stalled, client machine that is storing data to the IBM Spectrum Protect Server. With such slowly performing environments, the background IBM Spectrum Protect server process responsible for managing deletion of directory-container files might mistakenly interpret the directory-container file as being empty and remove it from the system.

Who is affected:

This issue affects all directory-container users of IBM Spectrum Protect server V7 and V8 levels

Recommendation:

Apply the fix for APAR IT26003

Problem Resolution:

APAR IT26003 will be resolved in the following IBM Spectrum Protect server levels. This is subject to change at the sole discretion of IBM:
7.1.9.200
8.1.6.100
8.1.7

If you require a fix before these levels become available, contact IBM Software Support.

Identifying affected data:

To determine if your system has been affected, run the following db2 commands as the server instance user:

db2 connect to tsmdb1
db2 set schema tsmdb1
db2 "select count(sdac.chunkid) as count,sdac.cntrid,sdac.poolid from sd_all_chunks sdac where not exists (select 1 from sd_containers sdc where sdac.cntrid=sdc.cntrid) group by cntrid,poolid for read only with ur"

If any records are returned, there is data affected by this condition. Contact IBM support for further steps.
