Changing Administrative Passwords

The documentation that came with your model of the ProCurve switch describes how to set the administrative password.

If you change the ProCurve switch administrative password and the HP XC system has more than one ProCurve switch, you must change every ProCurve switch to the same password.

	CAUTION: Changing the ProCurve password can cause complications if you do not also update the configuration and management database (CMDB) manually with the new password. Updating the CMDB is beyond the scope of this document. If you make an error updating the CMDB, you can corrupt the database and jeopardize system operation; for example, some commands might cease to function. If you must update the CMDB, be sure that you back it up as described in “Backing Up the Configuration Database” before changing the ProCurve switch administrative password.

The documentation that came with your model of the Quadrics Elan switch describes how to set the administrative password.

Generally, you can change the password by logging in to the switch and using its Quadrics Switch Control main menu as in the following example:

Enter 1-9  and press return: 8



                          1. Passwd settings
                          2. Access protocol settings

Enter 1,2  and press return: 1

The documentation that came with your model of the Voltaire InfiniBand switch describes how to set the administrative password.

Generally, you change the Voltaire Infiniband switch administrative password by logging in to the switch as admin and using its command interface as in the following example:

# telnet IRON00
IR0N00 login: admin
Password:

Welcome to Voltaire Switch IR0N00

connecting
IR0N00> enable
password:
IR0N00# ? pass
password update [admin, enable]password update [admin, enable]
IR0N00# password update admin
Insert new (up to 8 characters)password:
Please retype new password:
OK
IR0N00# password update enable
Insert new (up to 8 characters)password:
Please retype new password:
OK
IR0N00#

Also, enter the following command to set up ssh as root on the switch, which will enable you to access the root switch without a password:

# cat /root/.ssh/id_dsa.pub | ssh IR0N00 cat '>>' /.ssh/authorized_keys

Accessing the root switch without a password is necessary for the proper operation of the ip_prodmode_mon monitoring utility and the sys_check infiniband component.

Repeat these steps for each switch controller card, for example, for IRON00, IRON01, and so on.

The InfiniBand switches run Linux and have a root password. Occasionally, you might have to log into the InfiniBand switch as root, so HP recommends that you use the following procedure to change the default root password on the InfiniBand switches:

The instructions for changing the administrative passwords for Cisco® SFS 7000 Series InfiniBand Server Switches are located in the documentation for the specific switch model. Some of this documentation is available at the following web address:

http://docs.hp.com/en/highperfcomp.html

Additionally, you can access the full complement of Cisco documentation for the SFS 7000 Series InfiniBand Server switches at the following web address:

The following table lists default accounts for three Cisco SFS 7000 Series InfiniBand Server switches.

Allow access to the head node's management port through the external IP address, and synchronize the management port passwords as shown by the following procedure:

	NOTE: Substitute the node name (for example, n144) for the headnode variable.

If the head node's console port is connected internally, use the ipmitool command as follows to synchronize the console port password throughout the HP XC system:

# pdsh -a 'ipmitool -I lan -P "oldpassword" \
  -H cp-$(nodename) user set password 1 newpassword'
