When you plan an outage of a TrueCopy primary and secondary systems at the same time, the primary system must be powered off first, and then powered on last.
- Perform the planned outage of the primary system first. Because a planned outage does not affect pairs, nothing out of the ordinary must be done regarding the TC system or operations. Do not power on the primary system at this time.
- If a secondary system to be powered off is connected to a primary system that is not powered off, split the pairs before powering off the secondary system. Confirm that the pair status changes.
- Perform the planned outage of the secondary systems as described in Planned outage of the secondary system or remote path.
- Power on the secondary systems. Make sure that secondary systems and remote connections are fully operational and ready to resynchronize operations before powering on the primary system.
- Power on the primary system, and make sure the primary storage system and remote connections are operational and ready to resynchronize operations. If you split any pairs in step 2, you can also resynchronize those pairs now.
