D Using the iSCSI CLI

The CLI enables you to perform a variety of iSCSI or iSCSI/FCoE module management tasks through

an Ethernet or serial port connection. However, HP P6000 Command View should be the primary

management tool for the iSCSI and ISCSI/FCoE modules. The CLI is a supplemental interface.

Logging on to an iSCSI or iSCSI/FCoE module

You can either use Telnet or Secure SHell (SSH) to log on to a module, or you can log on to the

switch through the serial port. To log on to the module using Telnet:

On the workstation, open a command line window.

Enter the telnet command followed by the IP address:

= telnet <ip address>

NOTE:

This is the management port IP address of either iSCSI controller 01 or 02, and may

be a static IP, a DHCP provided IP, or a default static IP.

A Telnet window opens and prompts you to log in.

Enter an account name and password.

To log on to a module using SSH:

NOTE:

SSH works in a way similar to Telnet, except it uses ROSA to encode transmissions to

and from your workstation and the HP iSCSI or iSCSI/FCoE module.

On the workstation, open a command line window.

Enter the

ssh

command followed by the module mgmt port IP address:

# ssh <ip address>

An SSH window opens and prompts you to log in.

Enter an account name and password.

To log on to a switch through the serial port:

Configure the workstation port with the following settings, using an RJ45 to DB9 dongle (HP

spares part number 663678–001) and a standard RJ45 Ethernet cable:

•

115200 baud

•

8-bit character

•

1 stop bit

•

No parity, and flow control—none

When prompted, enter an account name and password (typically,

guest

and

password

Understanding the guest account

iSCSI and iSCSI/FCoE modules come from the factory with the guest account already defined.

This guest account provides access to the module and its configuration. After planning your

management needs, consider changing the password for this account. For information about

changing passwords, see the

“passwd command” (page 210)

. The guest account is automatically

closed after 15 minutes of inactivity. For example:

guest

[email protected]'s password: *********
