Risk categories

Function Loss

Affected Domain

Any TS7700 (3957-VED, 3948-VED and 3948-VEF) in mixed code level grid environments or capable of copy export or DS8K object offload capabilities. The affected code levels are R5.4 PGA1 (8.54.1.27), R5.4 PGA2 (8.54.2.17) and R6.0 GA (8.60.0.115).

Abstract

Problems were found in the following scenarios:
  • TS7700 (3957-VED, 3948-VED and 3948-VEF) in mixed code level grid environments with code levels R5.3 PGA1 (8.53.1.21), R5.4 PGA1 (8.54.1.27), R5.4 PGA2 (8.54.2.17) and R6.0 GA (8.60.0.115).
  • TS7700 (3957-VED, 3948-VED and 3948-VEF) with copy export or DS8K object offload capabilities with code levels R5.4 PGA1 (8.54.1.27), R5.4 PGA2 (8.54.2.17) and R6.0 GA (8.60.0.115).

Description

In a mixed code level grid environment where one or more of the clusters is in code level R6.0 GA (8.60.0.115) and the remaining clusters are in lower codes levels such as R5.3 PGA1 (8.53.1.21), R5.4 PGA1 (8.54.1.27) or R5.4 PGA2 (8.54.2.17), the R6.0 GA (8.60.0.115) cluster is not capable of going online.
Other failing functionalities are copy export or DS8K object offload capabilities with code levels R5.4 PGA1 (8.54.1.27), R5.4 PGA2 (8.54.2.17) and R6.0 GA (8.60.0.115) for both stand-alone and grid.

Recommended Action

Supported code levels for VTD_EXEC 414v1.04 install:
  • R5.4 PGA1 (8.54.1.27)
  • R5.4 PGA2 (8.54.2.17)
  • R6.0 GA (8.60.0.115)
Scenarios where VTD_EXEC 414v1.04 needs installation:
  • All clusters within a grid that get an upgrade to R6.0 GA (8.60.0.115) (even if VTD_EXEC 414v1.04 was installed before the upgrade).
  • Clusters capable of copy exports - in grid or stand-alone
  • Clusters capable of DS8K object offload - in grid or stand-alone
Scenarios where VTD_EXEC 414v1.04 does not need installation:
  • Any stand-alone cluster with code level R5.4 PGA1 (8.54.1.27), R5.4 PGA2 (8.54.2.17) and R6.0GA (8.60.0.115) that does not use copy export or DS8K object offload functionalities.
  • Any cluster with code level R5.4 PGA1 (8.54.1.27) and R5.4 PGA2 (8.54.2.17) that does not use copy export or DS8K object offload functionalities even if it is on a grid.
  • Any cluster with code level R5.3 PGA1 (8.53.1.21) or R5.4 GA (8.54.0.68)
