36 Detailed End-to-End iSCSI Setup
6 Configuring NICs for iSCSI traffic in the PowerVault NX1950 storage
solution in cluster mode— If you are setting up PowerVault NX1950
cluster solution as an iSCSI Target, perform the following prerequisites:
–
Follow the steps listed in the section Creating a Highly Available
iSCSI Target in the Dell PowerVault NX1950 Cluster Systems
Installation and Troubleshooting Guide on the Dell Support website at
support.dell.com.
– Turn off the firewall in all cluster nodes to ensure proper iSCSI Target
configuration. You can turn on the firewall after successful Target
configuration. You can configure Active/Active clustering to provide
high availability for iSCSI storage using 3.1 iSCSI Target. The
following steps outline the procedure for 3.1 iSCSI Target
configuration.
You can configure the cluster environment for Active/Active iSCSI target
access using the iSCSI Software Target option in the PowerVault NX1950
Management Console. As a part of the initial configuration, you must
perform the following tasks:
–
Create a highly-available instance (resource group) for Active/Active
clustering. Use the iSCSI Software Target MMC interface to create a
iSCSI highly-available instance.
– Highly-available instances are used to manage iSCSI Target resources,
including iSCSI Targets, iSCSI Virtual Disks, snapshots, and
schedules. You have the option of creating new highly-available
instances for iSCSI storage or use previously-configured highly-
available instances. You can use the same resource group to provide
high availability for both file sharing and block sharing.
– Configure the IP addresses for the iSCSI highly-available instances. If
you do not configure the cluster environment to support Active/Active
clustering, iSCSI Target software creates iSCSI Targets and iSCSI
Virtual Disks in a non-clustered environment by default.
