Abstract

DS8880 command hang leads to temporary loss of access

Content

With DS8880 R8.3 (88.3x.x.x) and later code streams, running in a z/OS environment with Global Mirror, and at DFSMS HDZ2210 or higher with OA52080 applied; the DS8880 could experience a temporary hang of I/O on the Primary until an automated warmstart clears the condition. If the condition occurs, the host could report the following messages: IOS071I Start pending, IOS450E path taken offline.

Fix and Mitigation
Apply APAR OA55379 to prevent this condition.
Information about the fix and the PTF's can be obtained from: http://www-01.ibm.com/support/docview.wss?crawler=1&uid=isg1OA55379
