IT32540: NO PERFORMANCE DATA COLLECTED WHEN STORAGE DEVICE PASSWORD CONTAINS $ SPECIAL CHARACTER. [DEGRADED DATA COLLECTION]

IBM Spectrum Control 5.3.7 (May 2020)

APAR status

• Closed as program error.

Error description

• Having a special character, such as $, in the storage device
  password causes the performance monitor to fail. The failing
  performance monitoring will show up as degraded data
  collection. The following errors were found.

  This issue
  applies to both Storage Insights and Spectrum Control
  

Local fix

• 1. Modify password on storage device so that it does not
  include $.
  2. Adjust the connection details in Storage
  Insights.
  3. Restart the performance monitoring job.
