IOP Multi-Boot Options During the IOP boot process, the IOP multi-boot options for the Windows operating system are displayed on the boot loader menu. These options allow you to choose the system root that you want to use. Note: Do not boot your IOP in any mode other than Operational Endurance I/O Processor Mode without explicit instructions from your service provider or without following the information described in the Endurance documentation. The Endurance-installed multi-boot options for an IOP are described in Table 2-1. Table 2-1 Multi-Boot Options for IOPs Multi-Boot Option Description Operational Endurance I/O Processor Mode Offline Endurance I/O Processor Mode This option is the normal operating mode for the IOP. This option boots a copy of Windows that contains and activates the Windows operating system and Endurance software. This is the only mode that allows an IOP to join the Endurance server. This option is for installation and performing maintenance. This option boots the Windows operating system and some Endurance software services. As a result, redirected SCSI devices are available locally (at the IOP), and the IOP is not active in the Endurance server configuration. Both IOPs must be active for the Endurance server to be fully fault tolerant. Note: Network adapters that are redirected are not accessible when booting in Offline Endurance 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 a Microsoft networking protocol, such as NetBEUI or TCP/IP. Endurance Overview 2-11
