Can anyone point out how I can overcome this problem? I've recently installed an additional 2.2GB disk in my RS/6000 C10, and I wanted it to be included in the rootvg volume group. I followed through the SMIT screen to add this disk to rootvg (the fast path is "extendvg rootvg hdisk1" where hdisk1 is my new disk. By the way, volume group rootvg has currently 1 PV of size 2 GB. However, the command was not performed successfully and the error message that was displayed is:
0516-050 linstallpv: Not enough descriptor area space left in this volume group. Either try adding a smaller PV or use another volume group.
0516-628 extendvg: Warning, cannot install PV hdisk1 in VG rootvg.
I think I need to increase the VGDA (volume group descriptor area) size somehow. But how? Any advice is greatly appreciated.
