Administrator Guide

• IP Address: For IPv4 or IPv6, the port IP address. For corresponding ports in each controller, assign one port to one subnet and
the other port to a second subnet. Ensure that each iSCSI host port in the storage system is assigned a different IP address. For
example, in a system using IPv4:
○ Controller A port 2: 10.10.10.100
○ Controller A port 3: 10.11.10.120
○ Controller B port 2: 10.10.10.110
○ Controller B port 3: 10.11.10.130
• Netmask: For IPv4, subnet mask for assigned port IP address.
• Gateway: For IPv4, gateway IP address for assigned port IP address.
• Default Router: For IPv6, default router for assigned port IP address.
8. In the Advanced Settings tab of the panel, set the options that apply to all iSCSI ports:
• Enable Authentication (CHAP): Enables or disables the use of the Challenge Handshake Authentication Protocol (CHAP).
Enabling or disabling CHAP in this panel updates its setting in the Configure CHAP panel (available in the Hosts topic by selecting
Action > Configure CHAP. CHAP is disabled by default.
NOTE: CHAP records for iSCSI login authentication must be defined if CHAP is enabled. To create CHAP records,
see Configuring CHAP.
• Link Speed:
○ Auto – Auto-negotiates the proper speed.
○ 1 Gb/s – Forces the speed to 1 Gbit/sec, overriding a downshift that can occur during auto-negotiation with 1-Gbit/sec HBAs.
This setting does not apply to 10 Gbit/sec HBAs.
• Enable Jumbo Frames: Enables or disables support for jumbo frames. Allowing for 100 bytes of overhead, a normal frame can
contain a 1400-byte payload whereas a jumbo frame can contain a maximum 8900-byte payload for larger data transfers.
NOTE:
Use of jumbo frames can succeed only if jumbo-frame support is enabled on all network components in the
data path.
• iSCSI IP Version: Specifies whether IP values use Internet Protocol version 4 (IPv4) or version 6 (IPv6) format. IPv4 uses 32-bit
addresses. IPv6 uses 128-bit addresses.
• Enable iSNS: Enables or disables registration with a specified Internet Storage Name Service server, which provides name-to-IP-
address mapping.
• iSNS Address: Specifies the IP address of an iSNS server.
• Alternate iSNS Address: Specifies the IP address of an alternate iSNS server, which can be on a different subnet.
CAUTION: Changing IP settings can cause data hosts to lose access to the storage system.
9. Perform one of the following:
• To save your settings and continue configuring your system, click Apply.
• To save your settings and close the panel, click Apply and Close.
A confirmation panel appears.
10. Click OK.
Managing scheduled tasks
The Manage Schedules action is enabled when at least one scheduled task exists.
When accessed, you can modify or delete scheduled tasks to:
• Create virtual snapshots
• Reset virtual snapshots
• Enable or disable drive spin down (DSD) for non-ADAPT linear disk groups
• Run virtual replications
NOTE:
You can only create a task and schedule to enable or disable DSD through the CLI, though you can modify the
schedule through the PowerVault Manager. For more information, see the Dell EMC PowerVault ME4 Series Storage
System CLI Guide .
Modify a schedule from the Home topic
Perform the following steps to modify a schedule:
1. In the Home topic, select Action > Manage Schedules.
