HYDIN0169E (OP0169) The cache type is out of cache space. The total used, space usage TiB, is less than 1 TiB from the total cache space or less than 5% below the total cache space, total space TiB.

Explanation

The free cache space is less than 1 TiB or 5% of total cache space.

Any subsequent scratch mount request will fail with completion and reason codes that indicate insufficient cache resources. Specific volume mounts will be allowed, but write operations to the volume will fail as if the volume were write protected.

The TS7700 enters the Out of Cache State when the free cache space is less than 1 TiB or 5% of total cache space and exits this state when it enters the Limited Cache Free State. The TS7700 enters the Limited Cache Free State when the free cache space is less than 3 TiB or 15% of total cache space and exits this state when the free cache space is greater than 3.5 TiB or 17.5% of total cache space. For a TS7700T, the entry and exit criteria for the Out of Cache State and the Limited Cache Free State apply to the tapeless partition.

Operator response

  1. Increase the amount of free cache space to at least 3.5 TiB or 17.5% of total cache space.
