Filsystem & file size limit

[CDI Support]

Hi,

If anyone knows...

Env = hp-ux 11.00, L-Class server, VA7400 array 6TB.

Question 1. What is the max file and filesystem limit base OS ?

Question 2. How can I create 6TB Filesystem to store 5/6 800GB size files there ?

Thanks in advance ?

Max size is 1 TB.

Look at this thread

Check this document for supported file system and file sizes:
http://docs.hp.com/hpux/onlinedocs/5971-2383/5971-2383.html

As far as creating you VG and LV to store the files, I would create 6 different 1 TB file systems and have 1 file per file system. I think that will be the only thing you will be able to do.

11.x can handle the job, but there are some things you need to take some care with. vgcreate will not allow you to build anything this large with the DEFAULT parameters that it uses. The one to watch in particular is the max physical volumes parameter (default 16 if I recall correctly). I would also reduce the max logical volumes from 255 where this table space will be just a waste.

Hi Mainak,

Doesn't look like hp-UX support a filesystem of size 6TB. The max filesystem size supported is 1TB under 11.0.

Also take a look at this thread. There is support for a 2TB filesystem / file in 11i version 3.3 JFS, disk layout version 3/4.

Hope this helps.

Thank you very much for all your help.

Finally I have loaded HP-UX 11i and created multiple 2TB filesystems.

Thank you again.
