Backup of ZFS snapshots on Solaris Cluster with Legato/EMC Networker
This describes how to setup a backup of the Solaris Cluster resource group named sample-rg.
The structure of my RGs is always:
RG: <name>-rg ZFS-HASP: <name>-hasp-zfs-res Logical Host: <name>-lh-res Logical Host Name: <name>-lh ZPOOL: <name>_pool
I used the bash as shell.
Define variables used in the following command lines
# NAME=sample
# RGname=${NAME}-rg
# NetworkerGroup=$(echo ${NAME} | tr 'a-z' 'A-Z' )
# ZPOOL=${NAME}_pool
# ZPOOL_BASEDIR=/local/${RGname}
Define a resource for Networker
What we need now is a resource definition in our Networker directory like this:
# mkdir /nsr/{bin,log,res}
# cat > /nsr/res/${NetworkerGroup}.res <<EOF
type: savepnpc;
precmd: "/nsr/bin/nsr_snapshot.sh pre >/nsr/log/networker_precmd.log 2>&1";
pstcmd: "/nsr/bin/nsr_snapshot.sh pst >/nsr/log/networker_pstcmd.log 2>&1";
timeout: "08:00am";
abort precmd with group: Yes;

Set some variables

NSR_SERVER="nsr-server"
ZPOOL="sample_pool"
RG="${NSR_CLIENT%-cl}-rg"
ZONE="${NSR_CLIENT%-cl}-zone"
Look for a valid backup
# /usr/sbin/mminfo -s ${NSR_SERVER} -o t -N /local/${RG}/cluster_config/nsr_backup
Restore ZFS configuration
# /usr/sbin/recover -s ${NSR_SERVER} -c ${NSR_CLIENT} -d /tmp -a /local/${RG}/cluster_config/nsr_backup/ZFS_Setup.sh

Follow the instructions in /tmp/${RG}.ClusterCreateCommands.txt:
Recreate sample-rg:
/usr/cluster/bin/clrg create -i /tmp/sample-rg.clrg_export.xml sample-rg
Add the following entries to all nodes!!!:
/etc/inet/hosts:
10.29.7.96 sample-cl
Recreate sample-lh-res:
/usr/cluster/bin/clrs create -i /tmp/sample-lh-res.clrs_export.xml sample-lh-res
Recreate sample-hasp-zfs-res:
/usr/cluster/bin/clrs create -i /tmp/sample-hasp-zfs-res.clrs_export.xml sample-hasp-zfs-res
Recreate sample-emctl-res:
/usr/cluster/bin/clrs create -i /tmp/sample-emctl-res.clrs_export.xml sample-emctl-res
Recreate sample-oracle-res:

Registering new resource type LGTO.clnt
1. Install Solaris client package LGTOclnt 2. Register new resource type in cluster. One one node do:
# clrt register -f /usr/sbin/LGTO.clnt.rtr LGTO.clnt
Now you have a new resource type LGTO.clnt in your cluster.
Create client resource of type LGTO.clnt
So I use scripts like this:
# RGname=sample-rg
# clrs create \
-t LGTO.clnt \
-g ${RGname} \
-p Resource_dependencies=$(basename ${RGname} -rg)-hasp-zfs-res \
-p clientname=$(basename ${RGname} -rg)-lh \
-p Network_resource=$(basename ${RGname} -rg)-lh-res \
-p owned_paths=${ZPOOL_BASEDIR} \
$(basename ${RGname} -rg)-nsr-res
This expands to:
# clrs create \
-t LGTO.clnt \
-g sample-rg \
-p Resource_dependencies=sample-hasp-zfs-res \
-p clientname=sample-lh \
-p Network_resource=sample-lh-res \
-p owned_paths=/local/sample-rg \
sample-nsr-res
Now we have a client name to which we can connect to: sample-lh
