Creating The File Systems; Setting The I/O Timeout Parameter - HP XP20000/XP24000 Configuration Manual

Creating the file systems

Create the file system for each new logical volume on the disk array. The default file system types
are:
HP-UX OS version 10.20 = hfs or vxfs, depending on entry in the /etc/defaults/fs
file.
HP-UX OS version 1 1.0 = vxfs
HP-UX OS version 1 1.i = vxfs
To create file systems:
1. Use the newfs command to create the file system using the logical volume as the argument.
Example 1
# newfs /dev/vg06/rlvol1
newfs: /etc/default/fs
mkfs (hfs): Warning -272 sectors in the last cylinder are not
allocated.
mkfs (hfs): /dev/vg06/rlvol1 - 2400256 sectors in 3847 cylinders
of 16 tracks,
2547.9MB in 241 cyl groups (16 c/g, 10.22Mb/g,
Super block backups (for fsck -b) at:
16, 10040, 20064, 30038, 40112, 50136, 60160, 70184, 80208, 90232, ...
2396176
Example 2
# newfs /dev/vg06/rlvol1
newfs: / etc/default/fs
mkfs (hfs): ...
:
7188496, 7198520, 7208544
#
Example 3
# newfs -F vxfs /dev/vg06/rlvol1
:
# newfs -F hfs /dev/vg06/rlvol2
2. Repeat step 1 for each logical volume on the disk array.

Setting the I/O timeout parameter

Set the I/O timeout value for each disk device to 60 seconds.
1. Verify the current I/O timeout value using the pvdisplay command:
Example
# pvdisplay /dev/dsk/c0t6d0
- - - Physical volumes - - -
PV Name
VG Name
PV Status
Allocatable
VGDA
Cur LV
PE Size (Mbytes)
Total PE
Free PE
Allocated PE
Stale PE
IO Timeout (Seconds)
2. If the I/O timeout value is not 60, change the value to 60 using the pvchange -t command:
determine the file system type
create file system
determine the file system type
Specify file system type
/dev/dsk/c0t6d0
