The slice is waiting for server 10.34.70.30 to NFS exports those mounts and make them available.
It does this by executing a cron job every 5 minutes.

# crontab -l
0,5,10,15,20,25,30,35,40,45,50,55 * * * * sh /opt/opsware/oi_util/bin/configure_exports.sh > /dev/null 2>&1

You can also run that shell script manually.  What it does is update the /etc/exports file to include the IP of the slice.

i can see the crontab entry like this: 

crontab -l
# Begin Opsware crontab entries (do not edit)
0,5,10,15,20,25,30,35,40,45,50,55 * * * * sh /opt/opsware/oi_util/bin/configure_exports.sh > /dev/null 2>&1 

also when i run that script manually it runs but installation is still stuck in this phase :

Waiting for ogfs store to become available from 10.34.70.30:/var/opt/opsware/ogfs/export/store
This can take up to 10 minutes.

I am still facing the same issue, it's not giving any error ,just stuck in "Waiting for ogfs store to become available from 10.34.70.30:/var/opt/opsware/ogfs/export/store" phase. When i check /etc/exports i can see the entries like this : cat /etc/exports
#Begin Opsware Distribution Export
/opt/SA/T8900-15076/T8900-15076-primary/disk001 *(ro)
#End Opsware Distribution Export

/var/opt/opsware/word 10.34.70.30(rw,no_root_squash,sync)
# End Opsware ogfs exports (do not edit) 

but nothing in /var/opt/opsware/ogfs/export/store directory
