Celerra:
delete_share document contains all the share names that needs to be removed. Do all verification carefully before doing reclaims.
1) Verify if there are any active connections to Celerra from client
Server_netstat server_2
Look after cifs and nfs connections
Make sure associate connections will be cleared before reclaim starts
2) Delete exports
for i in `cat delete_share`; do echo $i; server_export server_2 -unexport -perm $i; done
3) Remove replications if any exists
nas_replicate -list
nas_replicate -delete replication_name -mode both/source/destination
4) Unmount file systems
for i in `cat delete_share`; do echo $i; server_umount server_2 -perm /$i
5) Delete mount points
for i in `cat delete_mountpoint`; do echo $i; server_mountpoint server_2 -delete /$i; done
6) Delete File systems
for i in `cat delete_fs`; do echo $i; nas_fs -delete $i
7) Delete Luns from VG8
for i in `cat delete_luns`; do echo $i; nas_disk -delete device_name -perm
** make sure device status in use to false **

1. Get the list of thin devices bound in the NAS pool:
symcfg -sid xx show -pool poolname -thin -detail -gb |grep tdev
2. Get the list of FA ports that these thin devices are mapped to
for i in `cat devs`; do symdev -sid XX show $i |grep FA; done
Validate the mapping info gathered from the above step
symcfg lis -dir XX -p X -address -avail
3. Write disable the devices
for i in `cat devs`; do symdev write_disable $i -celerra -sid XX -nop; done
Check for no errors on command exit.
4. Unmap the thin devices from all the directors
for i in `cat devs`; do symconfigure -sid XX -cmd "unmap dev $i from dir all:all emulation=CELERRA_FBA;" commit -nop; done
Check for no errors on command exit.
5. Validate that the unmapping is successfull.
for i in `cat devs`; do symdev show $i -sid XX |grep FA; done
Check for N/A listed for FA on the command exit
6. Unbind the thin devices from the thin pool
for i in `cat devs`; do symconfigure -sid 47 -cmd "unbind tdev $i from pool NAS-AR-R62;" commit -nop; done
Check for no errors on command exit.
7. Validate that the unbinding is successfull.
for i in `cat devs`; do symdev show $i -sid XX |grep Pool; done
Check for N/A listed for Pool on the command exit
8. Get the list of data devices in the NAS pool:
symcfg -sid xx show -pool poolname -thin -detail -gb |grep tdat
9. Disable the data devices from the NAS Pool
for i in `cat debs`; do symconfigure -sid xx -cmd "disable dev $i from pool pool name, type=thin;" commit -nop
10. Reve data devices from the NAS Pool
for i in `cat devs`; do symconfigure -sid XX -cmd "remove dev $i from pool poolname, type=thin;" commit -nop
11. Add the data devices to the Prod SATA Pool
for i in `cat devs`; do symconfigure -sid XX -cmd "add dev $i to pool poolname, type=thin, member_state=ENABLE;" commit -nop
12. Validate that the devices have been successfully added to the Pool
symcfg -sid xx show -pool PROD-AR-R62 -thin -detail -gb
13. Initiate the Pool Rebalance
symconfigure -sid XX -cmd "start balancing on pool XXXX;" preview/commit -nop
14. Validate that the Rebalance is successfull.
symcfg -sid xx show -pool PROD-AR-R62 -thin -detail -gb
Check for "Balancing" for Pool state
14. Verify the growth in the Pool size
