Procedure: Resetting superuser password
You can reset the superuser password to the default password of passw0rd by
using a USB key command action.
You can use this procedure to reset the superuser password if you have forgotten
the password. This command runs differently depending on whether you run it on
a node canister that is active in a clustered system.
Note: If a node canister is not in active state, the superuser password is still
required to log on to the service assistant.
It is possible to configure your system so that resetting the superuser password
with the USB key command action is not permitted. If your system is configured
this way, there is no work-around. Contact the person who knows the password.
To use a USB key to reset the superuser password, see “USB key and Initialization
tool interface” on page 33.
If the node canister is active in a clustered system, the password for superuser is
changed on the clustered system. If the node canister is not in active state, the
superuser password for the node canister is changed. If the node canister joins a
clustered system later, the superuser password is reset to that of the clustered
system.
Procedure: Identifying which enclosure or canister to service
Use this procedure to identify which enclosure or canister must be serviced.
Because of the differences between the enclosures, you must be able to distinguish
between the control enclosures and the expansion enclosures when you service the
system. Be aware of the following differences:
v The model type that is shown on the labels. Model types 2076-112, 2076-124,
2076-312, and 2076-324 are control enclosures. Model types 2076-212 and
2076-224 are expansion enclosures.
v The model description that is shown on the left end cap. The description shows
either Control or Expansion.
v The number of ports at the rear of the enclosure. Control enclosures have
Ethernet ports, Fibre Channel ports, and USB ports on the canisters. Expansion
enclosures do not have any of these ports.
v The number of LEDs on the power supply units. The power supply units in the
control enclosure have six LEDs. The power supply units in the expansion
enclosure have four LEDs.
Identify the enclosure. An enclosure is identified by its ID and serial number.
v The ID is shown on the LCD panel on the front left of the enclosure. The serial
number is also found on the front left end cap of the enclosure and is repeated
on the rear left flange of the enclosure. The enclosure ID is unique within a
Storwize V7000 system. However, if you have more than one Storwize V7000
system, the same ID can be used within more than one system. The serial
number is always unique.
Note: Use the Manage Device options from the management GUI to change the
ID of an enclosure. Use this option to set a unique ID on all your enclosures.
