volinstall

volinstall(8)						      System Manager's Manual						     volinstall(8)

NAME

       volinstall - Sets up Logical Storage Manager (LSM) environment after LSM installation

SYNOPSIS

       /usr/sbin/volinstall

DESCRIPTION

       The volinstall script sets up LSM special device files, and add the following lines to the /etc/inittab file:

       lsmr:s:sysinit:/sbin/lsmbstartup  -b  </dev/console  >/dev/console  2>&1  lsm:23:wait:/sbin/lsmbstartup -n </dev/console >/dev/console 2>&1
       vol:23:wait:/sbin/volreconfig -n </dev/console >/dev/console 2>&1

       The first line calls the /sbin/lsmbstartup script, which enables LSM to start automatically on system reboot. The  second  line	calls  the
       /sbin/volreconfig script, which handles any pending encapsulation requests.

       If /sbin/lsmbstartup is not added to the /etc/inittab file, LSM must be started manually after system reboot.

									  Note

       The  volinstall script is automatically invoked by the volsetup, clu_create, and clu_add_member commands. Therefore, running the volinstall
       script to set up LSM is usually not necessary.
