Re: No enough PE per PV
See this whitepaper for details:
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01920387/c01920387.pdf (BSC link updated by admin)
Or are you talking about something else?

Re: No enough PE per PV
If you are running 11.23 or 11.31, then Duncan's link to 'vgmodify' and/or the 11.31 manpages will enable you to calculate a value.
If you are running 11.11 (or earlier) see Technical Knowledge Base # emr_na-c01037913
There in are tables of maximum max_pe values for various disk configurations.

Re: No enough PE per PV
I wonder about this:
Max PV 144
Cur PV 4
Do you really plan to add 140 disks to this VG?
Hope this helps!

Torsten.

Re: No enough PE per PV
No we don't plan on 144 disks....but I would like to figure out/calculate how many free PEs I would have if I brought that number down to say 20 or 30.

SolutionSo, you need to modify the Max PE per PV to 25600 (25600*16=409600) in order to use a 400GB LUN. In future, if there is a requirement for higher size LUNs, then increae Max number of PEs to yet higher value (32000 for 500GB LUN).
man vgmodify (read it carefully)
Regards.

Re: No enough PE per PV
PV physical volume (= disk or LUN)
Max PV 144
Cur PV 4
Now you have 4 disks (LUNs)
Max PE per PV 14076
PE Size (Mbytes) 16
Total PE 41907
You have a total of 670GB.
Alloc PE 40219
Free PE 1688
27GB are still free and unassigned.
Hope this helps!
Regards
Torsten.

Sorry if I take a long time to respond but I am getting errors every time I post, that's if it posts at all! Very frustrating.....
