Hello experts, I would like consult you some questions regarding RFE 6334757 and CR 6322205 (disk write cache).
========================================== RFE 6334757 disk write cache should be enabled and should have a tool to switch it on and off CR 6322205 Enable disk write cache if ZFS owns the disk ========================================== The cu found on SPARC Enterprise T5140, "Disk Write cache" was disable when it was shifted from Sun factory, but after install ZFS, "Disk Write cache" turned to be enable. My questions are 1) When SPARC Enterprise T5140 was shifted from factory, is the value of Disk Write cache set to disabled, right ? From RFE 6334757, we can see it is disable when shifted from factory, but I am not sure.. 2) On Solaris10, after installing ZFS and Zone, will the value of Disk Write cache be set to enable ? After what action is done, the value of Disk Write cache will be changed ? From CR 6322205, we can see as long as ZFS owns the disk, "Disk Write cache" will be set to enable, but what is the operation for "ZFS owns the disk" ? CR 6322205 Enable disk write cache if ZFS owns the disk 3) If change the value of Disk Write cache from enabled to disable, is there any impact/problem to the system ? 4) For FRU parts, Write cache has been set to disabled, right ? Thank you very much.
