Managing the iSCSI service on storage system interfaces
Command to use
You can use the iscsi interface command or FilerView to manage the iSCSI service on the storage system's Ethernet interfaces. You can control which network interfaces are used for iSCSI communication. For example, you can enable iSCSI communication over specific gigabit Ethernet (GbE) interfaces.
By default, the iSCSI service is enabled on all Ethernet interfaces after you enable the license. It is recommended that you do not use 10/100 megabit Ethernet interfaces for iSCSI communication. The e0 management interface on many storage systems is a 10/100 interface.
Displaying iSCSI status on storage system interfaces
Displaying iSCSI interface status using the command line
To display the status of the iSCSI service on storage system interfaces, complete the following step.
Step
|
Action
|
|---|
|
1
|
On the storage system console, enter the following command:
iscsi interface show [-a|interface]
-a specifies all interfaces. This is the default.
interface is list of specific Ethernet interfaces, separated by spaces.
Example
The following example shows the iSCSI service enabled on two storage system Ethernet interfaces:
iscsi interface show
Interface e0 disabled
Interface e9a enabled
Interface e9b enabled

Displaying iSCSI interface status using FilerView
To display the status of the iSCSI service on storage system interfaces, complete the following step.
Step
|
Action
|
|---|
|
1
|
Click LUNs > iSCSI > Manage Interfaces.
Result
The iSCSI status of all storage system Ethernet interfaces is displayed.

Enabling iSCSI on a storage system interface
Enabling iSCSI on an interface using the command line
To enable the iSCSI service on an interface, complete the following step.
Step
|
Action
|
|---|
|
1
|
On the storage system console, enter the following command:
iscsi interface enable {-a | interface ...}
-a specifies all interfaces.
interface is list of specific Ethernet interfaces, separated by spaces.
Example
The following example enables the iSCSI service on interfaces e9a and e9b:
iscsi interface enable e9a e9b

Enabling iSCSI on an interface using FilerView
To enable the iSCSI service on an interface, complete the following steps.
Step
|
Action
|
|---|
|
1
|
Click LUNs > iSCSI > Manage Interfaces.
|
|
2
|
Select the check box for each interface you want to enable.
|
|
3
|
Click Enable, and then click OK.
|
Disabling iSCSI on a storage system interface
Disabling iSCSI on an interface using the command line
To disable the iSCSI service on an interface, complete the following step.
Step
|
Action
|
|---|
|
1
|
On the storage system console, enter the following command:
iscsi interface disable [-f] {-a | interface ...}
-f forces the termination of any outstanding iSCSI sessions without prompting you for confirmation. If you do not use this option, the command displays a message notifying you that active sessions are in progress on the interface and requests confirmation before terminating these sessions and disabling the interface.
-a specifies all interfaces.
interface is a list of specific Ethernet interfaces, separated by spaces.
|
Disabling iSCSI on an interface using FilerView
To disable the iSCSI service on an interface, complete the following steps.
Step
|
Action
|
|---|
|
1
|
Click LUNs > iSCSI > Manage Interfaces.
|
|
2
|
Select the check box for each interface you want to disable.
|
|
3
|
Click Disable, and then click OK.
|
Displaying the storage system's target IP addresses
The storage system's target IP addresses are the addresses of the interfaces used for the iSCSI protocol.
Displaying target IP addresses using the command line
To display the storage system's target IP addresses, complete the following step.
Step
|
Action
|
|---|
|
1
|
On the storage system console, enter the following command:
iscsi portal show
Result
The IP address, TCP port number, target portal group tag, and interface identifier are displayed for each interface.
Example
toaster> iscsi portal show
Network portals:
IP address TCP Port TPGroup Interface
10.60.128.99 3260 1 e9a
10.60.128.100 3260 2 e9b
|
Displaying target IP addresses using FilerView
To display the storage system's target IP addresses, complete the following step.
Step
|
Action
|
|---|
|
1
|
Click LUNs > iSCSI > Portal Addresses.
Result
The IP address, TCP port number, target portal group tag, and interface identifier are displayed for each interface.
