Re: VA7100

Hi
If I dont remember wrong there was a 128GB filesystem limit in 11.0 (with vxfs). I am quite sure I had larger filesystems then 80GB.

Re: VA7100

I'm guessing your getting this error in your vgcreate command ? If that's the case what actually happened is the default 4MB extent size is probably not enough to store the LVM data structure because you got such a huge number of physical extents that needs to be stored in the LVM data structure. Try to increase your pe_size in your vgcreate command .. start with 8 if it does not like it increase it to 16, 32, 64 and so on until it stop complaining (check man vgcreate)
# vgcreate -s 8 /dev/vgXX /dev/dsk/cXtYdZ

Answering the other question ..
Depending on your JFS version these are the limits ..
Version 3
- Supports 128GB FS and 128GB files on 10.20
- Supports 1TB FS and 1TB files on 11.0 & above
Version 4
- Supports 1TB FS and 1TB files on 11.0

Robert,

Make sure if you're using SAM that you have the patch PHCO_23436. This is for the interaction between SAM and vxfs for the 1TB filesystem that S.K. mentioned.

HTH,
