Qlogic Online Data Migration Using the iSR6200 in Cluster Configurations (ISR651405-00 A, December 2011)

6 – Inserting the Router into a Solaris Cluster
ISR651405-00 A 8
If you are inserting the router for an ESX node in a VMware cluster, follow these steps instead of the
procedure in the user’s guide:
1. In the original configuration, ensure that the VM was created on a common datastore, and that the VM
is currently running on the ESX-Host 1.
2. While I/O is running, check the path status and ensure that both paths are active.
3. In the vSphere™ Client, click the Configuration tab.
4. In the left pane, click the Storage menu, and then click the Devices tab.
5. In the right pane, click the View menu, click each device, and then click the Manage Paths link to verify
the available paths and their status.
6. Remove controller A direct paths by zoning out ESX ports from the controller A ports on the fabric.
7. Verify that I/O continues over controller B ports.
8. Add router-presented ports for controller A ports, and then zone them with ESX host ports.
9. Click the Manage Paths link, and then verify that additional paths are visible.
I/O may now either continue through controller B ports or fail back to controller A ports, as presented
by the router.
10.Remove the controller B direct paths by zoning out ESX ports from controller B ports on the fabric.
11. Verify that the I/O completely fails over to the router path without errors.
12.Add router-presented ports for controller B ports and zone them with ESX host ports.
13.Verify that the newly-added paths are seen in the Manage Paths link. If so, the router is completely
inserted in the data path.
14.Start the migration job for the shared devices.

Inserting the Router into a Solaris Cluster
Oracle
®
Solaris Cluster 3.3 implements both SCSI2 and SCSI3 (persistent reservations) for the shared
storage resources that it manages. By default, two-node clusters use SCSI2 reservation and multiple
cluster nodes use persistent reservation, but you can change this setting if needed. QLogic has tested both
SCSI2 and persistent reservation with Solaris cluster.
The iSR6200 supports Solaris 10 clusters on Solaris 10 platforms, any array model, Oracle Solaris
Multipath I/O (MPxIO), and router insertion method 2.
To insert the iSR6200 in the data path for Solaris clusters, use the procedures documented in
Appendix A of the Data Migration Service for iSR6200 User’s Guide. To insert the router in Solaris 10
nodes, follow these steps instead:
1. In the original configuration, ensure that all of the array paths are accessible by the cluster nodes.
2. While the I/O is running, check the path status by issuing the mpathadm list lu and luxadm
display commands.
3. Remove one of the direct paths from each cluster node by changing the zone on one of the fabrics.
4. Check the path status.
5. After the paths are removed on the host, add a router-presented target path.
6. Check the path status on the cluster nodes to ensure that the nodes show router-presented paths.
7. Remove the other direct path on the nodes by changing the zone on the second fabric.
