Using Clustershell to Transition LUNs from 7 to C

Wasn’t sure we could do it with Clustershell, but we definitely can in 8.3.1!

Step 1: Setup on 8.1.4 7-Mode Controller

# FAS1>

vol create SANTEST01 -l C.UTF-8 -s none aggr0 3g

vol options SANTEST01 no_i2p off

vol options SANTEST01 nvfail off

vol options SANTEST01 read_realloc off

vol status SANTEST01

lun create -s 2g -t windows_2008 -o noreserve /vol/SANTEST01/SANLUN01.lun

lun show /vol/SANTEST01/SANLUN01.lun

igroup create -i -t windows MS02 iqn.1991-05.com.microsoft:ms02

igroup show MS02

lun map /vol/SANTEST01/SANLUN01.lun MS02 11

lun show -m /vol/SANTEST01/SANLUN01.lun

lun show -v /vol/SANTEST01/SANLUN01.lun

snapmirror on

options snapmirror.access *

Note: The vol options bit isn’t necessary since they all default to off with the new volume, just here to demonstrate that these need to be off before transitioning from 7 to C.

2: Setup on 8.3.1 CDOT Cluster

# CLU1::>

volume create -vserver SVM1 -volume SANTEST01 -type DP -aggregate N1_aggr1 -size 3g

vserver peer transition create -local-vserver SVM1 -src-filer-name 10.10.10.95

snapmirror create -source-path 10.10.10.95:SANTEST01 -destination-path SVM1:SANTEST01 -type TDP

snapmirror initialize -destination-path SVM1:SANTEST01

snapmirror show -destination-path SVM1:SANTEST01 -fields state,status

igroup create -vserver SVM1 -igroup MS02 -protocol iscsi -ostype windows -initiator iqn.1991-05.com.microsoft:ms02

3: Cutover Steps on 8.1.4 7-Mode Controller

Shutdown servers and/or applications using the LUN, and then...

# FAS1>

lun unmap /vol/SANTEST01/SANLUN01.lun MS02

vol offline SANTEST01

4: Cutover Steps on 8.3.1 CDOT Cluster

# CLU::>

snapmirror update -destination-path SVM1:SANTEST01

snapmirror break -destination-path SVM1:SANTEST01

lun show -vserver SVM1 -path /vol/SANTEST01/SANLUN01.lun

lun offline -vserver SVM1 -path /vol/SANTEST01/SANLUN01.lun

lun modify -vserver SVM1 -path /vol/SANTEST01/SANLUN01.lun -serial BpEwz$Hb4Ryw

lun online -vserver SVM1 -path /vol/SANTEST01/SANLUN01.lun

lun map -vserver SVM1 -path /vol/SANTEST01/SANLUN01.lun -igroup MS02 -lun-id 11

5: Tidy up Steps on 8.3.1 CDOT Cluster

# CLU::>

snapmirror delete -destination-path SVM1:SANTEST01

6: Tidy up Steps on on 8.1.4 7-Mode Controller

# FAS1>

snapmirror release SANTEST01 SVM1:SANTEST01

7: Very final Tidy Up on 8.3.1 CDOT Cluster

# CLU::>

vserver peer transition delete -local-vserver SVM1 -src-filer-name 10.10.10.95

Proof of the pudding...
