"To many links" HP-UX 11.11

[mvr]

I'm getting this error (To many links) when trying to add additional space (drive to) vg01.

I understaned reason for this is that "Max PE = 16" in /etc/lvmtab (which is default).

The question is, how do I change "Max PE" to 255 with out of deleting and recreating vg01 in 11.11 version?

Is there a way to install "vgmodify" binary (which is available on 11.23 and higher), with out of upgrading OS?

Thank you,

Miro Vran

Talking about MAX PV by chance?

Please show your vgdisplay -v.

You maybe just have too many alternate pathes?

[mvr]

Thank you for looking in to this ... Here is an output from vgdisplay -v (also attached)

Alternate links do not count against your MAX PV parameter in a VG.

VGMODIFY does allow you to reset the MAX PV parameter on the VG.  However prior to HP-UX 11.31 the VG has to be deactivated before you use VGMODIFY.

I don't think VGMODIFY is available for general download.  It **MIGHT** be available somewhere online if you were to search via Google, but not guarantees.

[mvr]

Thank you for the reply. So if I get my hands on " vgmodify " binary, I would be able to use it on 11.11?

I do have support with "CSU Industries", but they never heard of using " vgmodify " on 11.11 and that's why Im looking for additional resources for advice ...

[Torsten.]

vgmodify is only supported with 11.23 and 11.31.

MAX PV is not counted for alternate paths, but there is a maximum for them too.

[Torsten.]

For vg01 you already hit the maximum of physical volumes:

Max PV 16
Cur PV 16
Act PV 16

[Patrick Wallek]

VGMODIFY is, or at least used to be, available for HP-UX 11.11 as I used it at a previous job.  I think I got it from HP support though.

I don't know if it is still available for 11.11 though.
