IT06063: NEGATIVE "PCT_UTIL" REPORTED FOR FILESPACE ON SERVER BECAUSE OF WRONG ESTIMATION BY CLIENT

IBM Tivoli Storage Manager (TSM) Client 7.1.2 Downloads and READMEs

APAR status

• Closed as program error.

Error description

• The Tivoli Storage Manager Backup Archive Client may wrongly
  calculate the free space available for a disk volume
  causing the filespace utilization percentage reported as
  negative in the output of "QUERY FILESPACE" command executed on
  Tivoli Storage Manager Server.
  Here is an example of "QUERY FILESPACE" output showing the
  problem:
  
  
              NODE_NAME: NODE1
         FILESPACE_NAME: \\remotedir\v$\abcd
           FILESPACE_ID: 2
         FILESPACE_TYPE: NTFS
               CAPACITY: 1048576.00
               PCT_UTIL: -99.60
               [...]
  
  In the above example, the Tivoli Storage Manager B/A Client has
  calculated that the disk "\v$" has 2 TB as "Free space" when the
  total space is 1TB.
  So the "PCT_UTIL" % value is shown as negative on Server.
  
  
  
  Tivoli Storage Manager Versions Affected:
  All Tivoli Storage Manager Backup-Archive client versions on
  Microsoft Windows platform
  
  
  
  Initial Impact:
  Medium
  
  
  
  Additional Keywords:
  TSM negative pct_util percentage utilization client server
