Windows Data Store: Recovering a Disk Path
If one of the paths defined in a Data Store become unavailable until the user
modifies the domain configuration:
• Loading of virtual volumes stored in other available paths will work.
• Loading for input a volume located in the lost path (not SCRATCH
according to DSM/TC or TMF) will:
o Succeed if the volume timestamp check is enabled and a
restore script is configured and execute correctly.
o else the load will fail.
• Loading a SCRATCH volume for output will be successful if at least
one path remains available and the Volume Group is configured for
auto-scratch.
An error message will be logged to EMS each time the path in error is accessed.
To recover the files if there is no scripting, the user must restore the backups of
these volumes in other paths of the Data Store, in paths still available or in new
paths added in the configuration.
It is recommended to modify the Data Store disk pool configuration to remove
the problematic paths and add new paths as necessary. Virtual volume files must
be manually moved from path to be removed to new path if necessary.
