4 v Validate that the volume copies are identical, mark, and repair any differences that are found.
If you want to resolve any differences, you have the following options:
4
4 v Consider that one volume is correct and make the other volume copy match the other copy if any
differences are found. The primary volume copy is the copy that is considered correct.

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 that is active in a cluster.
v If the node is active in a cluster, the password for superuser is changed on the cluster.
v If the node is not in active state, the superuser password for the node is changed. If the node joins a
cluster later, the superuser password is reset to that of the cluster.
Note: If a node 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 cluster superuser password with the USB key
command action is not permitted. If your system is configured this way, there is no workaround. 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

Procedure: Identifying which enclosure or canister to service

4
Use this procedure to identify which enclosure or canister must be serviced.
4
Because of the differences between the enclosures, you must be able to distinguish between the control
4
enclosures and the expansion enclosures when you service the system. Be aware of the following
4
4 differences:
v The model type that is shown on the labels. Model types 112 and 124 are control enclosures. Model
4
types 212 and 224 are expansion enclosures.
4
4 v The model description that is shown on the left end cap. The description shows either Control or
4
Expansion.
v The number of ports at the rear of the enclosure. Control enclosures have Ethernet ports, Fibre Channel
4
ports, and USB ports on the canisters. Expansion enclosures do not have any of these ports.
4
4 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.
4
4 Identify the enclosure. An enclosure is identified by its ID and serial number.
4 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
4
4 enclosure ID is unique within a Storwize V7000 system. However, if you have more than one Storwize
4 V7000 system, the same ID can be used within more than one system. The serial number is always
unique.
