7 Managing servers with VIOM

station indicating that it is still waiting for these data. This process can be interrupted by disabling the VIOM managed status in iRMC user interface or BIOS interface.

At the end of this process the VIOM inventory data is freshly recreated (inven- tory boot), the VIOM virtualization data is rewritten by VIOM to the iRMC (also evaluating the new inventory data) and the virtualization data is made active via an init boot. As long as the virtualization data is not available to the server, this server will not be able to boot.

This illustrates that when managing PRIMERGY rack servers with VIOM it is very important that the VIOM management sta- tion is always running.

It is advisable to make regular backups of the ServerView Oper- ations Manager database and the VIOM database including trans- action logs. These database backups and transaction logs should be stored on high-availability storage media. Regular backups of the OS image of the ServerView management station should also be created so that the VIOM management station can always be rec- reated in the event of a server crash.

If the server needs to boot after AC failure even though the VIOM man- agement station is not currently available, the VIOM-managed status of this server must be deactivated (see also below). But if this is done, the I/O address virtualization of the server gets lost. The Virtual-IO Manager later detects that this server is no longer VIOM-managed by the VIOM-enabled flag in the iRMC. Because of this, the VIOM-managed status in the Virtual-IO Manager is changed to unmanaged in this case and, if a profile was assigned to this server, it is internally unassigned.

If a VIOM-managed PRIMERGY rack server is moved to a different location that is not controlled by the VIOM management station that originally con- trolled it, this PRIMERGY rack server cannot boot because it waits end- lessly for the virtualization data.

It is best to unmanage the PRIMERGY rack server in VIOM before moving it to the new location. If this is no longer possible, the VIOM-managed status can be deactivated in the iRMC user interface and the system BIOS.
