Hello Shiv,

The largest file you can have without large file support is 2GB. If you enable large file support you can go well beyond that. The command to enable large files is fsadm.
fsadm -F vxfs -o largefiles /mountpoint. Please see the man page for fsadm and fsadm_vxfs for more information.

Tom

It depends upon what version of vxfs you have.

hi

Unless you enable 'largefiles', the maximum file size is 2GB.

If you current file system has not been created to support large files, you need to run a special command that will enable this.

configuration file that is involved here is:
/etc/fstab

hope this helps too!

kind regards

hi again,

to enable largefile support on file systems that do not support it, you must do the following:

#fsadm -F vxfs -o largefiles /mount-point

edit /etc/fstab and update nolargefiles to largefiles.

hope this helps too!

kind regards

Hi Shiv,

Normally the largefile supported in 2GB.

If u enable largefiles support on the FS leval, then it is 2TB.
To enable the largefile support,

If u have online JFS then do

#fsadm -F vxfs -o largefiles /mountpoint.

If u dont have onlineJFS then do,

#umount /
#fsadm -F vxfs -o largefiles /dev/vgxx/rlvolx
#mount /dev/vgxx/rlvolx /mountpoint.

To check whether u have online JFS or not..

#swlist -l bundle |grep -i online

All the best..

Hi,

It depends on the filesystem which you are using.
VxFS can, theoretically, support files up to two terabytes in size. The maximum size tested and supported on HP-UX 11.x
systems is one terabyte. Large files are files larger than two gigabytes in
size.

You need to use # mkfs -F vxfs -o largefiles special_device size while creating the filesystem, for large file support. If you already created FS without -o largefiles, you can use fsadm with -o large option to change the current filesystem settings. And also you need to update /etc/fstab for the large file support.
