what is the different of file system between hpux 11.0 and 11.11

[豐順科技]

I have a L2000 which is installed hpux 11.0 and connect with va7100 directly,and I have configured a vg01 with there luns form va7100.
I wich if this L2000 has something worng, another server rp5470 which OS is hpux 11.11 would still mount the file system in vg01. I have tried before, and what my step proceed to vgimport and vgchange -a y in rp5470 is successful. But finally, I type mountall command that hpux 11i didn't work. I don't if the question is the file system format is different between hpux 11.0 and 11.11 or what my setp is worng. Please help me, thank you.

Hi,
The corresponding File system entries for your vg01 volume group should be there in the rp5470 /etc/fstab file then only mountall will work. Otherwise you need to mount the FS manually after doing vgimport and vgactivation.
Better way is see ur L2000 /etc/fstab and copy the corresponding vg01 FS lines in the rp5470 machine's /etc/fstab. Then mounall will work without any problem.

Vxfs and its relationship to the kernel are better on 11.11. You get better I/O. No commands are any different.

mount -a

The filesystems are not the issue here. Look elsewhere.

If you can see the LVOL then VxFS versions may very well be at issue here. The 11.0 box may still be using Version 3.00 Filesystem while the 11.11 box probably is already using version 4.0..

Try using fstyp on your 11.00 and 11.11 systems and compare:

ie.:

root@frfhpte3 # fstyp -v /dev/frfhpte3a/orarepo
version: 4
f_bsize: 8192
f_frsize: 1024
...
..

First - you don't want to have the volume group in the fstab of both servers. If they both reboot - they will both try to vgactivate the vg....

If they are not in MC/SG, then you need to unmount all file systems in /dev/vg01 and vgchange -a n /dev/vg01 on the L2000 first.

Then, vgchange -a y /dev/vg01 on the rp5470 and mount the filesystems manually....

Usually, the issue is the other way around - 11.11 is vxfs version 4 by default and 11.0 is vxds 3.0. If you create a filesystem on the 11.11 box, and you want to mount on the 11.0, then you have to do it like so on the 11.11 box (don't use newfs!):

mkfs -F vxfs -o largefiles -o version=3 /dev/vgXX/rlvol1
