Error description
In a Global Mirror environment, where there are more than one MTPPRC (multi-target PPRC) legs, then the first leg is removed, MSGIEA494I PPRC PAIR SUSPENDED messages are only issued once after an IPL. This only occurs when PPRCMT is disabled in DEVSUPxx parmlib member.
Local fix
Enable PPRCMT by the following: 1. Create a DEVSUPxx parmlib member 2. Copy the current DEVSUPxx parmlib member to the new member. 3. Add Enable(PPRCMT) Statement in the new DEVSUPxx member. 4. SET DEVSUP=xx to activate new member.
Problem summary
**************************************************************** * USERS AFFECTED: Users of D/T2107 storage subsystems that * * support Multi-Target PPRC with PPRCMT * * feature disabled. * **************************************************************** * PROBLEM DESCRIPTION: Missing IEA494I messages during GM * * suspend operation. * **************************************************************** * RECOMMENDATION: * ****************************************************************
Problem conclusion
When processing a State Change Interrupt on a 2107 storage subsystem that supports Multi-Target PPRC with PPRCMT feature disabled, IEA494I SUSPEND messages are not surfaced due to an incorrect assumption that a single PPRC relationship in a multi-target environment is always relationship 1. This presumption results in not resetting a flag used to prevent multiple instances of IEA494I SUSPEND messages to be surfaced. Checking is modified to determine hardware supports MTPPRC and resetting the flag when duplex/pending status has been done for 1 of 4 possible relationships. KEYWORDS: D/T2107 PPRC/K
