vxtunefs persistant across reboots

[hpuxrox]

If I make a setting change with vxtunefs does it stay after a reboot?

[Dave Olker]

man vxtunefs:

If /etc/vx/tunefstab exists, the VxFS-specific mount command invokes vxtunefs to set device parameters from /etc/vx/tunefstab.

Thanks Dave. I did some verification and the setting do go away after a umount/remount of the file system.

Post an example with screen output please.

# vxtunefs /mnt | grep max_diskq

max_diskq = 1048576

# vxtunefs -o max_diskq=16777216 /mnt

UX:vxfs vxtunefs: INFO: V-3-22525: Parameters successfully set for /mnt

# vxtunefs /mnt | grep max_diskq

max_diskq = 16777216

# umount /mnt

# mount /dev/vg00/lvtest /mnt

# vxtunefs /mnt | grep max_diskq

max_diskq = 1048576

And where in those steps did you add the desired paramter to the /etc/vx/tunefstab file?
