Present 2 Vdisk as one logical volume on one host
This may be simple question among you expert here. I have an EVA4400 and I wanna know if it's possible to present 2 vdisk as one logical volume on one host (a Windows 2003 host), or should I just use spanned volume on the host?
Thanks and regards.

No I don't think you can combine two vdisks at the EVA level.
You'd have to use a spanned volume on the host.

What is the reason you want to persent 2 vdisks in one logical volume instead of presenting one big Vdisk.

Re: Present 2 Vdisk as one logical volume on one host
And apparently I'm gonna use striped volume instead of spanned volume since each vdisk are already on vraid5. Any suggestions?

Re: Present 2 Vdisk as one logical volume on one host
- the controller firmware is quite new
- the disk group was created from this firmware AND
-- in enhanced mode
As far as I know, you cannot grow that virtual disk any further even with the most recent firmware, so it might not be a bad idea to use OS-level volume management. Then you can assign both 2TB virtual disks to both controllers and maybe enjoy better throughput.
