● 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 or modifying unused ports may cause hosts to lose access to the storage
system.

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.
2. Select the schedule to modify. The schedule settings appear at the bottom of the panel.
3. If you want to replicate the last snapshot in the primary volume, select the Last Snapshot check box.
The snapshot must exist at the time of the replication. This snapshot may have been created either manually or by
scheduling the snapshot.
NOTE: This option is unavailable when replicating volume groups.
4. Specify a date and a time in the future to specify when to run the scheduled task. This date and time is also the starting
point for any specified recurrence.
● To set the Date value, enter the current date in the format YYYY-MM-DD.
