HP-UX reviewer

naks, kala nyo genius ako sa HP-UX? Kodigo ko lang ito in case of emergency..ito ung laman ng halo-halo.txt na naka-save sa lagi kong dala na vintage 128mb flash disk tuwing may duty ako.

HP-UX: Disk and Filesystem tasks

• Search for attached disk
  ioscan -fnC disk
  

• Initialize a disk for use with LVM
  pvcreate -f /dev/rdsk/c0t1d0

• Create the device structure needed for a new volume group.
  cd /dev
  mkdir vgdata
  cd vgdata
  mknod group c 64 0x010000
  

• Create volume group vgdata
  vgcreate vgdata /dev/dsk/c0t1d0
  { if your expecting to use more than 16 physical disks use the -p option, range from 1 to 256 disks. }
  

• Display volume group vgdata
  vgdisplay -v vg01
  

• Add another disk to volume group
  pvcreate -f /dev/rdsk/c0t4d0
  vgextend vg01 /dev/dsk/c0t4d0
  
  
• Remove disk from volume group
  vgreduce vg01 /dev/dsk/c0t4d0
  

• Create a 100 MB logical volume lvdata
  lvcreate -L 100 -n lvdata vgdata
  newfs -F vxfs /dev/vgdata/rlvdata

• Extend logical volume to 200 MB
  lvextend -L 200 /dev/vgdata/lvdata
  

• Extend file system to 200 MB
  
  :: NO online JFS installed
  fuser -ku /dev/vgdata/lvdata { kill all process that has open files on this volume. }
  umount /dev/vgdata/lvdata
  extendfs /data
  
  ::Online JFS {ex. 200 MB / 4 MB = 50 LE; 50 x 1024 = 51200 blocks }
  fsadm -F vxfs -b 51200 /data

• Set largefiles to support files greater than 2GB
  fsadm -F vxfs -o largefiles /data
  

Paunawa:kung hindi maintindihan, magtanong sa katabing ofismate...more to come.
