HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)
Logging in using the serial link on the Onboard Administrator
If you are connected to a terminal server, you can log in through the serial link on the Onboard
Administrator.
Booting the system and individual server blades
Before booting the system, ensure that all of the system components other than the server blades—the
storage blocks and so on—are turned on. By default, server blades boot whenever power is applied
to the HP ExDS9100 performance block (c-Class Blade enclosure). If all server blades are powered
off (that is, in the standby state), you can boot the system as follows:
To boot the system:
1. Press the power button on server blade 1.
2. Log in as root to server 1.
3. To power on the remaining server blades, run the command: # exdsmgr boot server 2-
8
where 2-8 are the server blade numbers.
4. Run the exdsmgr show matrix monitors command to determine if export groups or virtual
host (vhost) IP addresses were disabled in preparation for the system being shut down.
5. If you had previously disabled export groups, enable them. For example, for the standard
exds_expg_default export groups, enable as follows:
# mx exportgroup enable exds_expg_default ALL_SERVERS
6. If you had previously disabled other virtual host (vhost) IP addresses, enable them as follows:
a. Use the exdsmgr show matrix command to identify the virtual host IP addresses.
b. Enable each vhost in turn. For example, to enable the 16.123.123.1 vhost, use this command:
# mx vhost enable 16.123.123.1
NOTE:
If a server blade is already powered on, the boot server command safely bypasses that server.
Rebooting a server blade
If you are using virtual host IP addresses to export NFS or Web services, you can reboot an individual
server blade with minimal impact on services. This is because the virtual host IP addresses that are
normally hosted by that server fail over to a backup server.
To reboot a server blade:
1. Shut down the server blade as shown in the following example:
# exdsmgr shutdown server glory3
where glory3 is the server blade to shut down.
When the command finishes, the server is powered off (that is, in the standby state).
