Cache writeback Issue in Stornext

HP_User3 — Thu, 06 Feb 2025 11:59:22 GMT

Hi I am working with a HPE ESL G3 Tape Library with Stornext Storage manager.

I am receiving a ticket on Stornext:

"Stornext client buffer cache writeback has been disabled due to an unrecoverable I/O error. Write performance will be degraded. Buffer cache writeback will re-enabled when the file system river is reloaded."

Can anyone please guide what this means. Is it some storage related issue or Stornext software issue? I've rebooted Stornext Metadata Controller Servers as well but this issue persists.

This looks like a SW issue. If this application runs on an Appliance. Then i would suggest to check the server/appliance for any HW issues.

WRT ESL, we have not seen this issue on this platform.

If there are no HW issues on the ESL then the issue must be worked from the SSM side.
