HP XC System Software Administration Guide Version 3.1

If you must change this password, be sure that you back up the CMDB as described in “Backing Up the
Configuration Database” (page 79). You also need to update the CMDB manually, which is beyond the
scope of this document.
13.8.3 Changing the Interconnect Password
The procedure to change the administrative password of the Interconnect switch depends on the
Interconnect switch:
• The ProCurve (Gigabit Ethernet) switch has an administrative password and requires an update to
the HP XC configuration and management database (CMDB).
• The Myrinet Interconnect switch has no administrative password.
• The Quadrics Elan4 Interconnect switch has administrative password and does not require an update
to the HP XC CMDB.
• The Voltaire InfiniBand Interconnect switch has administrative password and does not require an
update to the HP XC CMDB.
13.8.3.1 ProCurve Switch
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” (page 79) before changing the ProCurve switch administrative password.
13.8.3.2 Quadrics Elan4
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
