same disk space available display

Rupert_1 — Tue, 18 Oct 2005 05:11:39 GMT

Hi,
EVA5000, 2C18D, VCS3.028, new installation.
We created 2 diskgroups and created a few Vdisks in each DG.
But one of the DG shows raid5,raid1 and raid0 having the same disk size available.
The other DG seems normal; raid5 and raid0
show the same available disk space, while raid1 is diffierent.
Thks.

could it be that the size you see is ~2048 GB? If yes then it looks similar to the our eva 4000 at the beginnig. There a Vdisk can be maximum 2048GB. And because you have enough availible space it shows you for Vraid 1,5,0 the same size. Because you have enoough space to create a Vdisk Raid1 with 2048GB. At the time you will not have that much availible space it may tell you that you could build a vidks raid1 with 1800GB but maybe a VdiskRaid0 with stil 2048GB.

Hope that is what you have.

Rupert:

You have a 2C18D. Is it all filled up?

How many disks are in each disk group and what are the sizes?

What are the sizes of the vdisks you created?

What Burg has stated is fact. If you have enough space left to create a 2TB vdisk RAID1, then all will continue to display 2TB until you have less space, or not enough to make 2TB RAID1.

If the size is a different amount, less than 2TB, you may have a different issue.

Just to add a bit to Steven's answer. 2048GB is a limit for VDISK size. So if you have enough space for RAID1, then the number will be the same for all RAID configurations.
