Explanation
One of the two power supplies for the bare metal server that runs the IBM Spectrum Virtualize for Public Cloud software is not
functioning.
User Response
If the other power supply fails, you might lose the contents of the volume cache. To prevent this
problem, complete one of the following actions:
- Turn off the IBM Spectrum Virtualize for Public Cloud software
on the bare server. This forces the volumes in that I/O group to run in write-through mode, so no
customer data is cached on the server. When the software stops, the cache is flushed to backend
storage.
- Use the chvdisk to disable the cache for each volume in the I/O group. No
customer data will be cached, so no data is lost if the second power supply fails.
