• Software on localhost
• 
  /var/adm/sw/products/ - subdirectories for each product installed
  /var/adm/sw/patch/ - subdirectories for each patch installed
  /usr/sbin/swinstall - install software/patches to localhost
  /usr/sbin/swremove - remove software from localhost
  /usr/sbin/swlist - list software depots installed locally or at a remote depot
• Software to distribute elsewhere
• 
  /usr/sbin/swcopy - copy software to local depot for distribution
  /usr/sbin/swremove -d - remove software from a local depot
  /usr/sbin/swacl - modify access control lists of local software depots

• PATH

• /usr/bin 
  /usr/ccs/bin /usr/contrib/bin
  /usr/dt/bin     CDE only
  /opt/[dir]/bin  for each [dir] that exists
  

• MANPATH

• /usr/man
  /usr/share/man
  /usr/contrib/man
  /usr/dt/bin             CDE only
  /opt/[dir]/share/man    for each [dir] that exists.
          
  /usr/sbin/catman -w creates file /usr/share/lib/whatis that man -k uses

• Without LVM
• • Hard partitions are provided only for models of disks that were supported prior to release 10.0. Hard partitions will not be provided on disks introduced with 10.0 or later.
  • You will not be able to use a partitioned disk for your root disk. You will only be able to use a non-partitioned disk or LVM disk for this purpose.

          
  Special files: /dev/dsk/c0t3d0  - block device  
                                  - c=controller #
                                  - t=SCSI target #
                                  - d=almost always 0
                 /dev/rdsk/c0t3d0 - character device
                 /dev/rmt/0       - tape device
          To set up a new disk for use:
  /usr/sbin/newfs -F FStype /dev/rdsk/c0t3d0
          By default, short or long filenames will be used based on
          whatever the root filesystem is.
  /sbin/mount /dev/dsk/c0t3d0 /filesystem
  
  Add it to /etc/fstab for automatic mounting during every boot.
  

• With LVM

• /usr/sbin/pv*   
  /usr/sbin/lv*
  /usr/sbin/vg*
  /dev/[vol_grp]/[log_vol]        - block device
  /dev/[vol_grp]/r[log_vol]       - character device
  i.e.    /dev/vg01/lvol3
          /dev/vg01/rlvol3
          /dev/scratchvg/scratch
          /dev/scratchvg/rscratch
  
  To set up a new disk for use with LVM:
  
  /usr/sbin/pvcreate /dev/rdsk/c0t4d0
  /usr/sbin/vgextend /dev/vg01 /dev/dsk/c0t4d0
  /usr/sbin/lvcreate -n test -L 600 /dev/vg01     # creates 600Mb volume
  /usr/sbin/newfs -F hfs /dev/vg01/test
  /usr/bin/mkdir /test
  /sbin/mount /dev/vg01/test /test
  
  Add it to /etc/fstab for automatic mounting during every boot.

  Fields are: device special file, mount point, FS type, options, backup frequency (unused), fsck pass number.

  Root volume must have pass number 1 and other volumes must have > 1. Allowed FS types are: swap, swapfs, ignore, hfs, vxfs, cdfs, nfs, or lofs.
