syncro 3-phase snapclone sssu command

jpmartin — Mon, 12 Nov 2007 08:40:02 GMT

Hi,

there is no problem to create a container then a copy (3-phase snapclone) of a Vdisk in sssu commands, with write-thru before and write-back after.

So, i get for the sssu command to suynchronize the source Vdisk with its 3-phase snapclone.

May be documented in SSSU ref manual, but i don't find it.

Regards

Jean-Pierre

Not sure exactly which command you need

SET VDISK "\Virtual Disks\Prd30" WRITECACHE=writethrough

ADD CONTAINER CONTAINER30 DISK_GROUP="Disk Groups\FATA" REDUNDANCY=Vraid1 SIZE=20

ADD COPY "Prd30" VDISK="\Virtual Disks\Prd30\ACTIVE" CONTAINER=CONTAINER30 DISK_GROUP="\Disk Groups\FATA" NOWAIT_FOR_COMPLETION

Thank you for these commands,

but i think it is only for the 3-phase snapclone creation.

So, i want to know which command synchronize the source with the destination between the write-thru and the write-back cache of the source.

The ADD COPY command will create the snapclone and implicitly start the 'synchronization'. The write-through setting deals with a (potential) performance problem, not a data integrity issue.
