Resuming geographic mirroring

 

If you suspend geographic mirroring, resume it in order to reactivate mirroring between the production and mirrored copies again.

When you resume geographic mirroring, the production and mirror copies are synchronized concurrent with performing geographic mirroring. Synchronization can be a lengthy process. If a disk pool becoming unavailable interrupts synchronization, then synchronization will continue from where it was interrupted when the disk pool becomes available again. When an interrupted synchronization is continued, the first message (CPI0985D) states that the synchronization is 0% complete.

To resume geographic mirroring, follow these steps:

  1. In iSeries™ Navigator, expand My Connections (or your active environment).

  2. Expand the system that owns the production copy of the disk pool for which you want to resume geographic mirroring.

  3. Expand Configuration and Service > Hardware > Disk Units > Disk Pools.

  4. Right-click the Disk Pool you want to resume and select Geographic Mirroring > Resume Geographic Mirroring.

Use the Start DASD Management Operation (QYASSDMO) API to reduce the amount of time it takes to make a disk pool unavailable.
