  • VRMFs prior to 1.4.8.0
  • VRMFs prior to 1.5.1.1

Remediation/Fixes

MTMs VRMF APAR Remediation/First Fix
FlashSystem 840 MTM:
9840-AE1 &9843-AE1

FlashSystem 900 MTMs:9840-AE2 &9843-AE2
Code fixes are now available, the minimum VRMF containing the fix depends on the code stream:
Fixed Code VRMF
1.5 stream: 1.5.1.1
1.4 stream: 1.4.8.0
1.3 stream: 1.3.0.10
N/A FlashSystem 840 fixes and FlashSystem 900 fixes are available @ IBM’s Fix Central

Workarounds and Mitigations

Customers running the 1.3 code version should be aware that 1.3.0.10 is the last planned release for the 1.3 code stream and that it will no longer be supported from a security fix point of view going forward. These customers should consider upgrading to either 1.4.8.0 or 1.5.1.1 to pick up these security fixes in these newer code streams which will continue to be supported.
