vgchange: Too many links

[Torsten.]

Or do you have an EVA8000/8100 by chance?

The system type is HSV 210 & there are two versions - 6110 & 6200. I am seeing this in the CommandView EVA, is there any other way of checking the version of EVA?

[Torsten.]

HSV 210 is EVA8000 with 8 front ports. With 4 HBAs this makes 16 pathes.

6110 & 6200 are different firmware versions (both not up-to-date!)

However, IMHO it doesn't make sense to present all the ports to all the HBAs.

I would suggest to adjust zoning and/or presentation to "downsize" this to 8 pathes only - this will also solve your "problem".

Hi,

You can use SSSU
----------------
ls system full
systemtype ...........................: HSV210


from server

#ioscan -funCdisk |grep -i hsv

HSV 210 belongs to EVA 8000/8100

Look at the attachment, this is what you have (make host X and Z to a single server).

If you cut down the number of links by configuration, you have only the half left for each LUN - so if you have now 100 in summary, you have only 50 after this.


As you already know, you cannot use all them anyway.

hi,


try moving /etc/lvmtab to /etc/lvmtab.old and running vgscan to create a new lvmtab.

Thanks, this looks like a zoning issue, I will take this up with the SAN team. Thanks everybody for your inputs.
