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 11.0 = vxfs • HP-UX OS version 11.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 determine the file system type 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, 1600 ig/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 create file system newfs: / etc/default/fs determine the file system type mkfs (hfs): ... : 7188496, 7198520, 7208544 # Example 3 # newfs -F vxfs /dev/vg06/rlvol1 : # newfs -F hfs /dev/vg06/rlvol2 Specify file system type 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 /dev/dsk/c0t6d0 VG Name /dev/vg06 PV Status available Allocatable yes VGDA 2 Cur LV 1 PE Size (Mbytes) 4 Total PE 586 Free PE 0 Allocated PE 586 [OPEN-9] Stale PE 0 IO Timeout (Seconds) default [I/O timeout value] 2. If the I/O timeout value is not 60, change the value to 60 using the pvchange -t command: Configuring disk array devices 27
