Re: Can the # of pv's in a vg be changed on the fly
OR replace your PVs with bigger ones assuming you can evacuate all LVs from a PV if you have the space and replace that PV with a larger PV and continue doing with the rest of the 15 PVs. Lengthy process but at least you won't have downtime compared to the backup and rebuild approach suggested earlier.
Cheers!

Re: Can the # of pv's in a vg be changed on the fly
> Running 11i. Does not appear vgmodify exists.
The term "11i" could mean 11.11 or 11.23 or 11.31 (otherwise known as 11iv1, 11iv2, 11iv3).
The 'vgmodify' command is intrinsic to 11.31 and available on 11.23 with patch PHCO_40920 (originally introduced in patch PHCO_35524).

Re: Can the # of pv's in a vg be changed on the fly
Nancy,
In the past you could get a (unsupported) version of vgmodify from HP support ( http://h30499.www3.hp.com/t5/System-Administration/vgmodify/m-p/5063800#M437316 ). Not sure if it is still available or not but you might want to check.

Re: Can the # of pv's in a vg be changed on the fly
The reason that the max number of PVs is 16 is because this is the default value and is controlled by a tunable. However, I don't think that the vgmodify works on a 11.11 operating system. But on a 11.31 operating system the max no of pvs and max no of vgs can be changed and these parameters which were considered as "cast in concrete" attributes are no longer so. In fact the kernel tunable parameter maxvgs is obsolete on 11.31!
