/etc/rc.d/iscsictl script

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

	Hello,

	One of my NetBSD servers is connecte to two NAS (through iscsi) and I
want to write a robust iscsictl script.

	Today, both NAS has to be activ when server is powered up. If one of
these NAS is rebuilding its RAID volume, my script doesn't mount iscsi
volumes.

	My script :


legendre# cat iscsictl
#!/bin/sh
#
# $NetBSD: squid.sh,v 1.1 2020/01/04 10:57:18 taca Exp $
#
# PROVIDE: iscsictl
# REQUIRE: iscsid
# KEYWORD: shutdown

if [ -f /etc/rc.subr ]; then
        . /etc/rc.subr
fi

name="iscsictl"
rcvar=$name
command="/sbin/${name}"
pidfile="/var/run/${name}.pid"

case $1 in
start)
        sleep 5
        ${command} add_send_target -a 192.168.12.2:3260
        ${command} add_send_target -a 192.168.12.3:3260
        ${command} refresh_targets
        ${command} list_targets
        ${command} login -P `iscsictl list_targets | \
                awk '/192.168.12.2/ { print $1; }' | tr -d ":"`
        ${command} login -P `iscsictl list_targets | \
                awk '/192.168.12.3/ { print $1; }' | tr -d ":"`
        sleep 1
        mount -o rw,log NAME=bacula /opt/bacula
        mount -o rw,log NAME=video /opt/video
        /etc/rc.d/mountd reload
        ;;
stop)
        umount /opt/video
        umount /opt/bacula
#       for i in `iscsictl list_sessions | awk '/^Session/ { print $2; }' \
#                       | tr -d ':'`
#       do
#               ${command} logout -I $i
#       done
        ;;
*)
        echo "Usage: $0 {start|stop}" 1>&2
        exit 64
        ;;
esac
legendre#

	I want to do a loop somewhere to force this script to wait for both
NAS. Is something like

while [ `iscsictl list_targets | grep 3260 | wc -l` -ne 2 ]
do iscsictl refresh_targets; sleep 1; done

enough ?

	Second question. I want to disconnect iscsi devices. But this
disconnection should be done /after/ /etc/rc.d/bacula stop. I haven't
found any option in rcorder to be sure that /etc/rc.d/iscsictl stop is
called /after/ /etc/rc.d/bacula stop.

	Help will be welcome,

	JB
