Procedure: Resetting Superuser Password; Procedure: Identifying Which Enclosure Or Canister To Service - IBM Storwize V7000 Unified Problem Determination Manual

b. Ask the Ethernet network administrator to check the firewall and router
settings.
3. Please run svcinfo lsfabric and check that the host is seen as a remote port in
the output. If not, then do the following tasks in order:
a. Verify that Storwize V7000 Unified and host get an fcid on FCF. If not,
check the VLAN configuration.
b. Verify that Storwize V7000 Unified and host port are part of a zone and that
zone is currently in force.
c. Verify the volumes are mapped to the host and that they are online. See
lshostvdiskmap and lsvdisk in the CLI configuration guide for more
information.
4. If you still have FCoE problems, you can attempt the following action:
a. Verify that the host adapter is in good state. You can unload and load the
device driver and see the operating system utilities to verify that the device
driver is installed, loaded, and operating correctly.

Procedure: Resetting superuser password

You can reset the superuser password to the default password of passw0rd by
using a USB flash drive command action.
About this task
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 flash drive 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 flash drive to reset the superuser password, see "USB flash drive and
Initialization tool interface" on page 186.
See also "Problem: Unable to log on to the management GUI" on page 205.
Results
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.
