backup success

The golden image node will be rebooted in 30 seconds /opt/cmu/tmp/GUI/config.txt was rewritten

cmu>

where:

test_julien

is the name of the logical group containing the node being backed up.

sda1,sda5,sda9

are the partitions on the hard drive.

o185i195

is the node name.

Modifying a management card password

Modifies the management card password in the HP Insight CMU database.

cmu> modify_password ILOILOCMlo100i

For example:

cmu> modify_password lo100i

login> hp password> service

password successfully changed

cmu>

IMPORTANT: You can only change the password in the HP Insight CMU database. This command does not change the actual password of the card. The password is echoed during this command.

Discovering MAC address for new nodes

The scan_macs command enables discovering the MAC address for new nodes. Enter parameters interactively. For example:

cmu> scan_macs

Enter the number of nodes to scan: 2

Enter the first nodename: node1

Enter the prefix of the node: node

Enter the IP address of the first node: 16.16.184.115

Enter the netmask of the first node: 255.255.248.0

Enter the BMC type (ex. ILO, lo100i): ILO

Enter the IP address of the first BMC: 16.16.188.115

Scanning 2 nodes.

First nodename is 'node1'. The prefix is 'node'.

The first IP address is '16.16.184.115'. The netmask is '255.255.248.0'.

The BMC type is 'ILO'.

The first BMC IP address is '16.16.188.115'. Is this correct? ([y]/n): y

Scanning. Please be patient. This process can take up to 10 minutes...

Scanning complete. 2 nodes added, 0 nodes updated. cmu>
