Provides the alternate root path that is necessary to prevent the /etc/zfs/zpool.cache file from being populated.
Supplying this value keeps a node from importing the ZFS storage pool automatically when it restarts after a crash. Not importing the ZFS storage prevents concurrency violations and file system corruption.
If you do not provide a value for the AltRootPath attribute, VCS sets the $AltRootPath to "/" as a workaround. This workaround makes sure that the ZFS command
zpool import -R $ AltRootPath $ PoolName does not populate the zpool.cache file.
Type and dimension: string-scalar
