User manual SEAGATE NL35 FC INSTALLATION

[. . . ] Discharge static from all items near or that will contact the drive. Never use an ohmmeter on any circuit boards. · Turn off the power to the host system during installation. · Always use forced-air ventilation when operating the drive. [. . . ] A low level format, with verify turned on, may take over six hours to complete. Protect against power failure or other power interruptions during the format. Boot the system from a system floppy, CD, or from a previously installed hard disc drive if there is one. Formatting a drive erases all user data. Be sure that you understand this principle before formatting any hard disc drive. It is not necessary to format a drive that previously has been used to store data, unless your intention is to erase all user data. Seagate® is not responsible for lost user data. NL35 Series disc drives are designed to operate with a variety of operating systems. Please refer to your system or Fibre Channel host adapter (controller) manual for information about formatting and setting up the drive for use with your particular operating system.

Any time a drive is inserted or removed from a Fibre Channel loop, a short loop interruption occurs and the loop resynchronizes automatically to accommodate the added (or removed) drive. Drive startup options The drive's motor will start spinning the discs based on the status of two signals set by the host adapter. These two signals are called Start_1 and Start_2. There are four options as described below. Option Start_2 Start_1 Motor spin function 1 . . . . . . . . . . . Motor spins up when the host adapter sends the SCSI Start command. Motor spins up after a delay of 12 seconds times the physical address of the drive. Most systems that host only a couple of drives use option 1 to enable all of the drives to start up immediately when power is applied to the drives. Systems hosting larger numbers of drives may be configured to start drives at various times to avoid overloading the capabilities of the host system's power supply. If you want to change the startup option for the drive, please refer to the documentation provided with your Fibre Channel host adapter or host system.

See "Drive Startup Options" above for the four possible startup options. · Computer does not seem to recognize the drive. [. . . ]
