Generating a vg with alt path taking long time

[Craig A. Sharp]

I am trying to generate a set of volume groups with alternate paths.
This process is taking hours. Is this normal?
I would think that it would be seconds, not hours.

Thanks,

Craig

No, this is not at all normal and the command should complete in seconds.

Hello,

Could you please provide more info?

It depends on how disks you have to add to each volume group.

Are these vgs shared for an MC/ServiceGuard environment? Do you have a large number of disks in your array?

I have one thought. Is is possible that you are creating a volume group using a duplicate minor device number?

[Craig A. Sharp]

Well, it looks like it might be a hardware problem. I am getting lbolt errors on both the primary and alternate paths.

An engineer is coming out in the morning.

FYI, here is the command that I am using

vgcreate /dev/vg02 /dev/dsk/c5t0d0 /dev/dsk/c7tod0

Hi Craig:

As already noted, establishing a volume group with alternate (pv) links and/or adding them later (via 'vgextend') is a very quick operation normally.

You don't specify your release nor patch level. I presume you are running 11.0. In this case PHKL_26452 (and its successors) fix a variety of problems manifesting themselves as hung servers. I suggest you apply this patch, if applicable to your server, when you get a chance.

Regards!
