Installing IDE CD-ROMS You can install IDE CD-ROMs rather than SCSI CD-ROMs. If you install an IDE CD-ROM drive in one IOP, then you must also install an IDE CD-ROM drive in the other IOP. No variation on this hardware configuration is allowed. Configure the IDE CD-ROM drive as necessary to be accessible by the Windows operating system. If your server requires it, make sure that the IOP can boot from the IDE CD-ROM. You can assign the IDE CD-ROM drive to the IOP operating system and not configure it as redirected. You can also use the Endurance Configuration Utility to configure the IDE CD-ROM drive for redirection, on either IOP1 or IOP2, but not on both. If an IDE device malfunctions upon boot, the Windows operating system does not assign any SCSI resources to the IDE controller. Moreover, if no IDE devices are detected, the ATAPI driver is not loaded. This is different than SCSI devices, for which the Windows operating system loads the SCSI driver and assigns port numbers as long as a SCSI adapter is detected, even if no devices are attached to it. Unless promptly repaired, an IDE CD-ROM failure results in different SCSI port number assignments for all physical Host Based Adapters (HBAs) upon rebooting the IOP. This invalidates the Endurance configuration for the IOP with the failed CD-ROM device, thus preventing it from joining with the other IOP. In that case, the failed component must be repaired before the IOP with the failed CD-ROM can return to active status. Continue with Unpacking Your Endurance Server Kit (page 1-14).
