If you encounter this situation, verify the following items:
v
That an
satask_result.html
file is in the root directory on the USB key. If the
file does not exist, then the following problems are possible:
– The USB key is not formatted with the correct file system type. Use any USB
key that is formatted with FAT32, EXT2, or EXT3 file systems on its first
partition; for example, NTFS is not a supported type. Reformat the key or use
a different key.
– The USB port is not working. Try the key in the other USB port.
– The node is not operational. Check the node status using the LEDs. See
“Procedure: Understanding the system status using the LEDs” on page 198.
v
If there is an
satask_result.html
file, check the first entry in the file. If there is
no entry that matches the time the USB key was used, it is possible that the USB
port is not working or the node is not operational. Check the node status using
the LEDs. See “Procedure: Understanding the system status using the LEDs” on
page 198.
v
If there is a status output for the time the USB key was used, then the
satask.txt
file was not found. Check that the file was named correctly. The
satask.txt
file is automatically deleted after it has been processed.
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 176.
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.
