Using iSCSI

This chapter provides information on using iSCSI in MD Storage Manager. For iSCSI prerequisite requirements and detailed step-by-step instructions on setting up and configuring iSCSI, see the Installation Guide.

Using the iSCSI Tab

The iSCSI tab is shown in the MD Storage Manager only when the controllers contain iSCSI host ports. You can define or change settings for the iSCSI target or enter the CHAP permissions in the iSCSI tab. Here are some of the iSCSI settings:

•Change Target Authentication — Select the authentication method to be supported by the target.

•Enter Mutual Authentication Permissions — Define the permissions for initiators that require mutual authentication.

•Change Target Identification — Associate an alias with the target for simpler identification.

•Change Target Discovery — Modify the way to discover iSCSI targets using the Internet Storage Name Service (iSNS) server settings.

•Configure iSCSI Host Ports — Set the parameters for iSCSI host ports.

•View/End iSCSI Sessions — View iSCSI session details and end iSCSI sessions.

•View iSCSI Statistics — View and save iSCSI statistics.
