13.7.1 Sample Load Script for a DST Shadow Volume

The following is a sample load script for a DST pool cluster resource.

#!/bin/bash
. /opt/novell/ncs/lib/ncsfuncs

# activate the secondary pool
exit_on_error nss /poolact=ARCPOOL1

# activate the primary pool
exit_on_error nss /poolact=POOL1

# Optional delay to allow time for pools to activate before mounting the volume
sleep 10

#comment out the original volume mount command
#exit_on_error ncpcon mount VOL1=254

# Use the ncpcon mount command to create the shadow volume on mount
exit_on_error ncpcon mount VOL1=254,shadowvolume=ARCVOL1

exit_on_error add_secondary_ipaddress 10.10.10.38

exit_on_error ncpcon bind --ncpservername=NCS1-POOL1-SERVER --ipaddress=10.10.10.38

#This line is added if Novell CIFS is used as an advertising protocol
#novcifs --add ’--vserver=".cn=NCS1-POOL1-SERVER.ou=ncs.o=novell.t=AVALON_TREE."’ 
         --ip-addr=10.10.10.38

# If shadowfs is used, wait for shadowfs to start 
#for (( c=1; c<=10; c++ )) do 
# if [ ! -d /media/shadowfs/VOLUME/._NETWARE ]; then sleep 5; fi 
#done 

exit 0

13.7.2 Sample Unload Script

The following is a sample unload script for a DST pool cluster resource.

#!/bin/bash
. /opt/novell/ncs/lib/ncsfuncs

# This line is added if Novell CIFS is used as an advertising protocol
#novcifs --remove ’--vserver=".cn=NCS1-POOL1-SERVER.ou=ncs.o=novell.t=AVALON_TREE."’ --ip-addr=10.10.10.38 

# If shadowfs is used, unload the volume in FUSE 
#ignore_error fusermount -u /media/shadowfs/VOL1

ignore_error ncpcon unbind --ncpservername=NCS1-POOL1-SERVER --ipaddress=10.10.10.38

ignore_error del_secondary_ipaddress 10.10.10.38

# Deactivate the primary pool
ignore_error nss /pooldeact=POOL1

# Deactivate the secondary pool
ignore_error nss /pooldeact=ARCPOOL1

exit 0

13.7.3 Sample Monitor Script for a DST Volume

The following is a sample unload script for a DST pool cluster resource.

#!/bin/bash
. /opt/novell/ncs/lib/ncsfuncs

# Check the status of the secondary pool
exit_on_error status_fs /dev/pool/ARCPOOL1 /opt/novell/nss/mnt/.pools/ARCPOOL1 nsspool

# Check the status of the primary pool
exit_on_error status_fs /dev/pool/POOL1 /opt/novell/nss/mnt/.pools/POOL1 nsspool

exit_on_error status_secondary_ipaddress 10.10.10.38

# Check the status of the primary volume. Do not check secondary volume.
exit_on_error ncpcon volume VOL1

# This line is added if Novell CIFS is used as an advertising protocol
#exit_on_error rcnovell-cifs monitor

exit 0
