15 Reconfiguring the Hardware
This chapter describes how to make basic adjustments. It contains the following topics:
Changing Component Passwords
Oracle recommends that you change the passwords for the various rack components after the initial hardware and software configuration:

You can change the user accounts and GRUB passwords on the compute servers. default user accounts on a compute server are root
and the software owner account. Typically the software owner account is oracle
.
Changing the User Account Password
A compute server has two default user accounts: root
and the software owner (typically oracle
).
To change a user account password on a compute server:
Changing the Storage Server Passwords
The default user accounts on storage servers are root
, celladmin
, and cellmonitor
.
To change a user account password on a storage server:
Creating New Users and Changing Passwords on a PDU
The default account user for the power distribution unit (PDU) is admin
. You can create up to five users and set their passwords.
To create users and passwords on a PDU:
Changing the Oracle ILOM Password
The default user account for Oracle Integrated Lights Out Manager (ILOM) is root
.
To change the password for an Oracle ILOM user:
This example changes the password for user1
:
set /SP/users/user1 password Changing password for user /SP/users/user1/password... Enter new password:******** Enter new password again:******** New password was successfully set for user /SP/users/user1
Changing an InfiniBand Switch Password
The default user accounts on the InfiniBand switches are root
, ilom-admin
, ilom-user
, ilom-operator
, and nm2user
.
To change a password for a user on an InfiniBand switch:

Changing the Cisco Ethernet Switch Password
There are no user accounts on the Cisco Ethernet switch. The password, which is called the "enable" password, is not specific to a user account.
To change the password for the Cisco Ethernet switch:
Changing the Recovery Appliance Database User Password
Oracle recommends that you change the password of the Recovery Appliance default database user account.
To change the Recovery Appliance database user password:
-
Log in to the compute server as
rasys
. -
Issue the following RACLI command.
racli alter rasys_user --password
-
When prompted, enter and confirm the new password.
Enter rasys Password: Confirm new rasys Password:
The password specified for the Recovery Appliance user account must contain eight or more characters. Strong password authentication is used, so simple passwords are not allowed.

The OSB tape backup default accounts include the application users admin
and oracle
, and the encryption key wallet account.
To change an OSB tape backup application user password:
-
Log in to the compute server as
root
. -
Use the
obtool chuser
command.This example changes the password of the
admin
account:# obtool chuser -q admin Password:******** Password (again):******** #
To change the password for the OSB tape backup encryption key wallet:
-
Log in to the compute server as
root
. -
Run the following commands:
# export OBCONFIG=/osbcat/etc/obconfig # obcm chpass --keywallet Old wallet password:******** New wallet password:******** New wallet password (again):******** Wallet password has been reset #

You can change the configuration settings for the Domain Name System (DNS) servers after the initial setup. All servers and switches in Recovery Appliance must reference the same DNS servers. This section explains how to set the servers and switches to the same DNS servers. Oracle recommends changing the servers one at a time.
Changing the DNS Server Address on an InfiniBand Switch
To change the DNS server address on an InfiniBand switch, connect to Oracle ILOM and log in as the ilom-admin
user. You can choose from one of the following methods:
-
Oracle ILOM web interface
Select the Configuration tab and set the DNS server addresses.
-
Oracle ILOM CLI
Use the following command to set the DNS:
set /SP/clients/dns nameserver=dns_ip
In the preceding command, dns_ip is the IP address of the DNS server. For multiple servers, enter a comma-separated list. For example:
set /SP/clients/dns nameserver=dns_ip1,dns_ip2,dns_ip3
Changing the DNS Server Address on the Cisco Ethernet Switch
To change the DNS server address on the Cisco Ethernet switch:
Changing the chrony/NTP Servers
You can change the configuration settings for the chrony
implementation of the Network Time Protocol (NTP) servers after the initial setup. All servers and switches in Recovery Appliance must reference the same NPT servers, so that they are synchronized to the same time. This section explains how to set the Recovery Appliance servers and switches to the same chrony/NTP
server addresses. Oracle recommends changing each server one at a time.
This section contains the following tasks:
Note:
-
You must restart Recovery Appliance after completing these tasks.
-
You can configure one or two CHRONY servers for use with Recovery Appliance.
Setting the NTP Server Address on the Compute Servers
To set the chrony/NTP
server address on a compute server:
Setting the CHRONY Server Address on the InfiniBand Switches
Note:
InfiniBand switches are used for X8 and earlier compute servers of the Recovery Appliances. X8M and X9M use different network fabric switches.
Do not manually edit the files on the InfiniBand switches.
To set the chrony/NTP
server address on a Sun Datacenter InfiniBand Switch 36:
Set the NTP Server Address on the Cisco Ethernet Switch
To set the NTP server on the Cisco Ethernet switch:
Changing the Time Zone Settings
This section provides information about changing the time zones on Recovery Appliance after the initial configuration and deployment. You must modify the following components when changing the time zone settings:
-
Storage servers
-
Compute servers
-
Sun Datacenter InfiniBand Switch 36 switches
-
Cisco switch
Note:
Before changing the time zone settings, you must stop the cell services on the storage servers and the Oracle Clusterware Services.
The following tasks describe how to change the time zone settings on the components:
Changing the Time Zone Settings on the Storage Servers
Complete the setting changes to all storage servers before changing the settings on the compute servers.
To change the time zone setting on a storage server:
Change Time Zone Settings on the Compute Servers
To change the time zone setting on a compute server:
