EMC Symm Meta volume size differ on HPUX 11.i

[Deepak Seth_1]

i have created a meta volume of size 185 GB on emc symm . it only shows 151 gb on hpux host . Is there maximum limitation on hpux for a physical device ?

please help.

Shalom,

No, that is not the maximum size for a logical volume.

What has probably happened is one of the following:

1) Calculation error on screen.
2) Not enough physical extents in the volume group the volume is part of. It will probably be necessary to rebuild the volume group with vgcreate.

I suggest the -p and/or the -s parameter of vgcreate to insure there are enough physical extents to permit the drive to include all of the space.

-p changes the default number of physical volume in the volume group from 255 to a lower number, permitting more space allocation per physical drive.

No, it is in the order of TBs. How are you checking the LUN size ? diskinfo ?

The actual meta volume size is 182+ GB

Sounds like a question for EMC. The drive geometry or emulation is being interpreted wrong by HPUX.
