Write back Cache

[iman_1]

Dear All,

Is it possible to disbale nowriteback cache on the controller when the restore is currently happening ? Is this parameter dynamic ?

I am seeing drastic reduction in the performance of the restore of one of the disks due to which I would like to enable writeback cache.

Cheers,
Iman

The controller is HSD30 and OS is OpenVMS 6.2

What about:

1. Connect to controller through the CLI
CLI SET
2. Restore

3. Connect to controller through the CLI
CLI SET
for all previous WRITEBACK enabled units that were disabled

Dave,

I have done that, but what I want to know is does the change to writeback caceh be performed while the restore is running ?

Cheers,
Iman

Yes because the controller changes the value itself when battery gets bad.
