APAR status
Closed as program error.
Error description
Long delays from an ESSNI query will circumvent the re-query logic that is supposed to check whether the volume has a relationship after the session has once again reconnected to the device.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: * * TPC-R Users who have connect to a DS8000 HMC device can * * experience this if there is lots of network latency, network * * errors, or if the device is busy and takes longer to * * respond. * **************************************************************** * PROBLEM DESCRIPTION: * * | fix pack | 5.2.3-TIV-TPC-FP0000 - target 3Q 2014 | * * * * * * http://www-01.ibm.com/support/docview.wss?&uid=swg21320822 * * * * The target dates for future fix packs do not represent a * * formal * * commitment by IBM. The dates are subject to change without * * notice. * * * * Extra latency on the network can delay the response time * * from the DS8000 device and circumvent the re-query logic if * * the response takes more that one minute from the first * * query. * **************************************************************** * RECOMMENDATION: * * Check network and DS8000 to determine what is causing the * * network latency. * ****************************************************************
Problem conclusion
If defined relationships are found a new query will be driven to ensure that the state of the pair is up to date.
