Present the LUNs:
CAUTION:
Present only the disks that you wish to use with the VLS300 because existing data will be
destroyed during storage pool configuration.
a. In Command View EVA, in the Storage tab navigation tree, select the EVA for the VLS300 storage
system, Virtual Disks, the disk name that you want to present, then ACTIVE under that disk.
b. Select the Presentation tab.
c. Ensure that Write Protect is set to No.
d. Ensure that the Preferred path/mode is set to either Path A-Failover only or Path B-Failover
only (Figure 17).
NOTE:
Set the Preferred path/mode for half of the disks to Path A-Failover only, and to Path
B-Failover only for the other half of the disks. This balances the data traffic across
both A and B controllers. For more information on data traffic balancing, see
dual pathing.
