Re: EVA4400 : write-back not possible on VDISK !
check the cache batteries first, because if they are all low in both controllers, all writes are only write-through according to the cache policy...

Re: EVA4400 : write-back not possible on VDISK !
maybe the batteries of the owning controller are failed. Take off the front bezel of the controller assembly and take a look at the batteries. Other way: Physical view in the navigation pane of the CV and take a look at the controllers.
Best regards,
Patrick

Re: EVA4400 : write-back not possible on VDISK !
Have you presenetd the disk ??
For all the time I can remember across many versions of CV until you present the vdisk it will stay as write-through even if you try to change it.
Just present the vdisk and then it should be OK because the default is write-back.
