Problem
In the event of a failure and restoration of a storage connection, the paths may not become enabled automatically and manual intervention will be required to re-enable them. Even running commands such as 'vxdctl enable' and 'vxdisk scandisks' did not re-enable the paths. In the end it was necessary to run the 'vxdmpadm enable' command for each of these paths.
Error Message

However if upon checking a disk using 'vxdisk list', the paths are still showing up as disabled:
eg.
numpaths: 6
sdm state=enabled type=secondary
sdk state=enabled type=primary
sdl state=enabled type=secondary
sdf state=disabled type=primary
sdg state=disabled type=secondary
sde state=disabled type=primary
Solution
Solution:
Once the latest VRTSaslapm was installed and the test repeated, the paths were then re-enabled automatically.
At the time of this issue, version 6.0.400.101 of the VRTSaslapm package was the latest available version on https://sort.Veritas.com/asl/latest

RedHat 6.5
