APAR / IssueDESCRIPTION
APAR PI97018 Removing copy sets from a GM session might result in the consistency group bit being set for pairs remaining on the LSS.

An issue was found where removing the copy sets from a Global Mirror (GM) session resulted in the consistency group bit being set for the paths using the same LSS pairing. When CSM attempts to remove the copy set relationships from the hardware, it reestablishes the paths to ensure both the primary and secondary are cleaned up properly. The issue was that the reestablish of the paths was not checking to see whether the relationships were running in Global Copy mode, and automatically set the consistency group bit on. Any unexpected suspend event then resulted in a freeze condition for the duration of the extended long busy timer. This fix pack ensures that if no Metro Mirror pairs are using the paths, that the consistency group bit remains off when copy sets are removed from the session.

*** It is critical that any customer running Global Mirror sessions, upgrade both servers to the 6.2.2.1 level as soon as possible to avoid the issue. ***
APAR PI96534 Basic HyperSwap session types might fail to properly freeze the session during a HyperSwap event if paths were reestablished using the Copy Services Manager paths-management wizard.

Basic HyperSwap sessions require paths to be established with the consistency group bit enabled for all Metro Mirror pairs. An issue was found where a customer fixed an issue with logical paths between the storage systems using the Copy Services Manager GUI paths-management wizard, but the paths ended up being established without the consistency group bit enabled. This fix pack ensures that any time Copy Services Manager establishes paths, Basic HyperSwap sessions will enable the consistency group bit.

*** It is critical that any customer running Basic HyperSwap sessions, upgrade both servers to the 6.2.2.1 level as soon as possible to avoid the issue. ***
APAR Pi96257Suspending a CSM session while in Global Copy mode remains in Suspending state if there were path warnings during the command processing.

An issue was found where under certain circumstances running a suspend command while in Global Copy mode results in the session remaining in a Suspending state. When a session is running in Global Copy mode and a Suspend command is issued, the pairs are first established in Metro Mirror. When all pairs reach a Prepared state, a freeze is issued to the hardware to create a consistent copy of the data at the secondary site. An issue was found where a subset of the paths could not be established before establishing the pairs in Metro Mirror mode, resulting in a warning message for the Suspend command. The warning message prevented the code from going into the mode where it would wait for all pairs to reach a Prepared state. All pairs went Prepared, but due to the error the session, did not freeze the pairs and remained in a Suspending state.
Defect 72665Removing copy sets from a Copy Services Manager Global Mirror session resulted in the Master going fatal on the hardware

An issue was found where removing copy sets from a Global Mirror session might result in the Master session going fatal and no longer forming consistency groups. When the copy sets get removed, Copy Services Manager attempts to remove the pair from the LSS session before terminating the relationship on the hardware. An issue was introduced in 6.2.0, where Copy Services Manager might not wait until the pair has successfully been removed from the Master session. If Copy Services Manager terminates the relationships during the middle of a consistency group being formed, the Master might fail to form that consistency group and go into a fatal state. This fix pack ensures that the pair is successfully removed before terminating the relationships on the hardware.

*** It is critical that any customer running Global Mirror sessions, upgrade both servers to the 6.2.2.1 level as soon as possible to avoid the issue. ***
Defect 73198When issuing a Suspend command to the Global Mirror leg of a Multi-target Metro Mirror – Global Mirror (MM-GM) session, if the Master does not go into a Paused state, Copy Services Manager is not providing a Stop command to allow recovery at the remote site.

For Multi-target MM-GM sessions, a customer can Suspend the Global Mirror leg of the session, which issues a Pause to the Global Mirror Master on the hardware. If the Master cannot form a consistency group, it is possible that the session will remain in a Suspending state. For other session types, a Stop command can be issued, which forces the suspension of the Global Copy pairs, and allows the session to go into a Suspended state. This fix pack adds the Stop command for Multi-target MM-GM sessions while in the Suspending state.
