Maintenance requirements
This topic explains points to be noted regarding powering-off when FS is up and running. This
topic also explains points to be noted regarding offline microcode replacement.
Replacing the microcode offline
Microcode is usually replaced online. In the cases when it is replaced offline (for example, when
configuration of shared memory needs changing), pool and pair information in shared memory is
lost, and pools and pairs must be recreated.
Powering-off
Use the following process to power off:
1. Stop the host I/O.
2. Switch off the power supply.
When you restore the power, FS's behavior depends on whether data that was in shared memory
before powering off is present after powering on.
If information in shared memory before powering off is present after powering on
If information in the shared memory is present after switching off the power supply, the pools and
pairs can usually be used. However, since the storage system checks the status of the pools and
the pool volumes, if the pool volumes are blocked at that moment, the pool will be blocked and
the status of the pairs changes to “PSUE”. When this occurs, do the following:
1. Switch the power on.
2. Recover the pools.
