Offsets Name Length Format Description
0 0 S42SNTWR 4 binary Number of SyncIO write requests.
4 4 S42SNTWO 4 binary Number of SyncIO write requests that were completed synchronously.
8 8 S42SNTWS 4 binary Number of SyncIO write requests that are skipped for zHyperLink because of a previous asynchronous write.
12 C S42SNTWB 4 binary Number of SyncIO write requests that went asynchronous because of a busy link condition.
16 10 S42SNTWM 4 binary Number of SyncIO write requests that went asynchronous because of a cache miss.
20 14 S42SNTWP 4 binary Number of SyncIO write requests that went asynchronous because of an operation delay.
24 18 S42SNTWE 4 binary Number of SyncIO write requests that went asynchronous because of not having a complete write token set.
28 1C S42SNTWI 4 binary Number of SyncIO write requests that went asynchronous because of an invalid write token.
32 20 S42SNTWC 4 binary Number of SyncIO write requests that went asynchronous because of inconsistent writes.
36 24 S42SNTWD 4 binary Number of SyncIO write requests that went asynchronous because of zHyperLink writes being disabled on a device.
40 28 S42SNTWA 4 binary Number of read requests to a data set open for SyncIO writes.
