The admin account is the system administrator or superuser account. If
an administrator loses the password to this account, you can have a serious
security issue. As a result, the procedure to recover the password for the
admin account requires you to power cycle all fabric interconnects in a
Cisco UCS
instance.
When you recover the password for the admin account, you actually change
the password for that account. You cannot retrieve the original password for
that account.
You can reset the password for all other local accounts through
Cisco UCS Manager.
However, you must log in to
Cisco UCS Manager
with an account that includes aaa or admin privileges.
Caution
This procedure requires you to power down all fabric interconnects in
a
Cisco UCS
instance. As a result, all data transmission in the instance is stopped until
you restart the fabric interconnects.
Determining the Leadership Role of a Fabric Interconnect
Procedure
Step 1
In the
Navigation pane, click the
Equipment tab.
Step 2
In the
Equipment tab, expand
Equipment > Fabric
Interconnects.
Step 3
Click the fabric interconnect for which you want to identify the
role.
Step 4
In the
Work pane, click the
General tab.
Step 5
In the
General tab, click the down arrows on the
High Availability Details bar to expand that
area.
Step 6
View the
Leadership field to determine whether the
fabric interconnect is the primary or subordinate.
Verifying the Firmware Versions on a Fabric Interconnect
You can use the following procedure to verify the firmware versions on
all fabric interconnects in a
Cisco UCS
instance. You can verify the firmware for a single fabric interconnect through
the
Installed Firmware tab for that fabric
interconnect.
Procedure
Step 1
In the
Navigation pane, click the
Equipment tab.
Step 2
In the
Equipment tab, click the Equipment node.
Step 3
In the
Work pane, click the
Firmware Management tab.
Step 4
In the
Installed Firmware tab, verify that the following
firmware versions for each fabric interconnect match the version to which you updated the firmware:
Kernel version
System version
Recovering the Admin Account Password in a Standalone
Configuration
This procedure will help you to recover the password that you set for the admin account when you performed an initial system setup on the fabric interconnect. The admin account is the system administrator or superuser account.
Before You Begin
Physically connect the console port on the fabric interconnect to
a computer terminal or console server
Determine the running versions of the following firmware:
The firmware kernel version on the fabric interconnect
The firmware system version
Tip
To find this information, you can log in with any user account on the Cisco UCS instance.
Procedure
Step 1
Connect to the console port.
Step 2
Power cycle the fabric interconnect:
Turn off the power to the fabric interconnect.
Turn on the power to the fabric interconnect.
Step 3
In the console, press one of the following key combinations as it
boots to get the
loader prompt:
Ctrl+l
Ctrl+Shift+r
You may need to press the selected key combination multiple times
before your screen displays the
loader prompt.
Step 4
Boot the kernel firmware version on the fabric interconnect.
After the system image loads, log in to
Cisco UCS Manager.
Recovering the Admin Account Password in a Cluster
Configuration
This procedure will help you to recover the password that you set for the admin account when you performed an initial system setup on the fabric interconnects.The admin account is the system administrator or superuser account.
Before You Begin
Physically connect a console port on one of the fabric
interconnects to a computer terminal or console server
Obtain the following information:
The firmware kernel version on the fabric interconnect
The firmware system version
Which fabric interconnect has the primary leadership role and
which is the subordinate
Tip
To find this information, you can log in with any user account on the Cisco UCS instance.
Procedure
Step 1
Connect to the console port.
Step 2
For the subordinate fabric interconnect:
Turn off the power to the fabric interconnect.
Turn on the power to the fabric interconnect.
In the console, press one of the following key combinations
as it boots to get the loader prompt:
Ctrl+l
Ctrl+Shift+r
You may need to press the selected key combination multiple
times before your screen displays the
loader prompt.
Step 3
Power cycle the primary fabric interconnect:
Turn off the power to the fabric interconnect.
Turn on the power to the fabric interconnect.
Step 4
In the console, press one of the following key combinations as it
boots to get the
loader prompt:
Ctrl+l
Ctrl+Shift+r
You may need to press the selected key combination multiple times
before your screen displays the
loader prompt.
Step 5
Boot the kernel firmware version on the primary fabric
interconnect.
