vxfs version and disk layout version

[rayche]

Who can give me detailed information about the relationship between vxfs version and disk layout version ?

Hi Rayche ,

To check vxfs version you are using , use:

# fstyp -v /dev/vg00/lvolx

version: 3

Rayche ,

Also check the relationship between vxfs version and disklayout vesion details , for hp-ux versions :

Ex: For hp-ux :11.00 with JFS 3.1 , uses vxfs version of 3.1 and supports Disk Layouts 2,3 , and the default disk layout it support is 3.

check this out for details:

OK, so , in fact, when we install JFS in our HP-UX server ,the disk layout verion is determined at the same time, though we can change the version, right ?

Rayche,

Yes - the default disk layout is the highest disk layout version supported, and the rest of the versions are usually for backward compatibility, so that you can import the VGs you may have created with earlier version of disklayout. When creating new VGs you dont create with older version of disk layout unless you want to use the disks between current and older versions.
