APAR status
Closed as program error.
Error description
The SVC/Storwize 7.3 or later code has a new cache architecture: There is a separation of cache hit metrics between an upper and a lower cache. TPC will show 0 or close to 0 read cache hits for SVC/Storwize v7.3 or later. With the new cache design, the upper cache is only a write cache, so TPC will see 0 read hits. Affected Releases: All TPC versions using SVC/Storwize version 7.3 or later.
