Chapter 2. Best practices for troubleshooting
Troubleshooting is made easier by taking advantage of certain configuration
options and ensuring that you have recorded vital information that is required to
access your system.
Record access information
It is important that anyone who has responsibility for managing the system know
how to connect to and log on to the system. Give attention to those times when the
normal system administrators are not available because of vacation or illness.
Record the following information and ensure that authorized people know how to
access the information:
v
The management IP addresses. This address connects to the system using the
management GUI or starts a session that runs the command-line interface (CLI)
commands. The system has two Ethernet ports. Each port can have either an
IPv4 address or an IPv6 address or both. Record this address and any limitations
regarding where it can be accessed from within your Ethernet network.
v The service IP address of the node canisters on the control enclosures is used
only in certain circumstances. The service IP address connects to a node canister
in the control enclosure. Access to the address is sometimes required if the
canister has a fault that stops it from becoming an active member of the system.
Each of the two node canisters can have a service IP address that is specified for
Ethernet port 1. Each address can have either an IPv4 address or an IPv6
address or both. Ensure that the address specified for each node canister is
different.
v
The system password for user
superuser
. The password is required to access the
system through the service IP address. The authentication of superuser is always
local; therefore, the user ID can be used when a remote authentication server
that is used for other users is not available.
