Table 2-1 Multi-Boot Options for IOPs
Multi-Boot Option Description
Operational Endurance I/
O Processor Mode
This option is the normal operating mode for the IOP. This option boots a copy of
Windows NT that contains and activates Windows NT and software.
This is the only mode that allows an IOP to join the server.
Offline Endurance I/O
Processor Mode
This option is for performing maintenance, such as upgrading the system
configuration or system software. This option boots Windows NT and some
software services. As a result, redirected SCSI devices are available locally (at the
IOP), and the IOP is not active in the server configuration. Both IOPs must be
active for the server to be fully fault tolerant.
Note: Network adapters, floppy drives, and serial ports that are redirected are not
accessible when booting in Offline HP NetServer AA I/O Processor Mode. To
transfer files (for example, configuration files) between IOPs, do one of the
following:
- Using the virtual network, place the file on a CE disk. This method is
available only if the CE operating system is running and both IOPs
are active.
- Install Enhanced IL Networking.
- Reboot into Endurance Maintenance Mode.
IOP Maintenance Mode This option is for emergencies only. This option boots a copy of the original
Windows NT that you installed (before any software was installed).
