Checking Available Spare Disks

To avoid any loss of critical data, it is essential for a filer to always maintain a pool of spare disks that can replace the faulty disk when a disk failure occurs. A filer without any left spare disk will not be able to keep the level of data safety and performance in case of a disk failure.

The SpareDiskCount parameter of the SEN_NA_FILER class reports the number of spare disks available for each filer monitored with the solution. By default, a warning is triggered when no spare disk is available (SpareDiskCount is set to zero).
