Editing iSCSI port settings

Use this procedure to edit the iSCSI port settings.

When the iSCSI virtual port mode is enabled for a port, the following items cannot be set using Device Manager - Storage Navigator:

  • IPv4 Settings
  • IPv6 Mode
  • IPv6 Settings
  • TCP Port Number
  • Selective ACK
  • Delayed ACK
  • Maximum Window Size
  • Ethernet MTU Size
  • Keep Alive Timer
  • VLAN Tagging Mode
  • iSNS Server

To edit iSCSI ports for which the virtual port mode is enabled, use Command Control Interface. For details, see the Command Control Interface documentation.

Before you begin

  • The Storage Administrator (System Resource Management and Provisioning) role is required to perform this task.
  • The Security Administrator (View and Modify) role is required to perform this task.

CautionIt is best to enable LUN security on each port when configuring your storage system. Although you can enable LUN security on a port when host I/O is in progress, I/O is rejected with a security guard after enabling.

  1. Click Storage Systems, and then expand the Storage Systems tree.

  2. Click Ports/Host Groups/iSCSI Targets, and select the Ports tab.

  3. Select the desired port, and click Edit Ports.
