Magneto-Optical Disk Configuration Guidelines

This section identifies the device drivers that must be configured into HP-UX for it to communicate with single magneto-optical disks. If you are configuring a magneto-optical disk library or adding an optical disk to an existing magneto-optical disk library, refer to the section, "Magneto-Optical Disk Library Configuration Guidelines."

Table 5-2 “Magneto-Optical Disk Configuration Requirements” lists the device drivers required to configure a magneto-optical disk to single-ended SCSI interface for each supported architecture.

Table 5-2 Magneto-Optical Disk Configuration Requirements

Architecture	Interface Card	Interface and Device Drivers	Default Device File
Series 700 ^[1] (core I/O only)	(internal)	`sdisk`^[2]	`/dev/[r]dsk/c#t#d#[s#]`^[3]
Series 800 CIO^[1]	27147A	`scsi2`^[4] `disc3`^[5]	(same as above)
Series 800 HP-PB^[1]	28655A	`scsi1`^[6] `disc3`^[5]	(same as above)
^[1]The following optical disks [listed with their respective product ID strings returned by SCSI Inquiry] can be configured to a Series 700 single-ended SCSI interface, Series 800 CIO or HP-PB single-ended SCSI interface: C1701A [S6300.650A], C1701C [C1716C], C2550B [C1716T]. ^[2]Specifying `sdisk` causes `sctl`, `c700`, and `wsio` drivers to be included automatically in the kernel. ^[3]`c#t#d#[s#]` derives from `ioscan` output: `c#` is the card instance for the class of interface card to which the device is attached, `t#` is the address of the device on the interface, `d#` is the device unit number. `s#` specifies section number and is shown for backward compatibility; the entire disk (`s0`) is assumed when `s#` is unspecified. ^[4]Specifying `scsi2` causes `cio_ca0` to be included in the kernel. ^[5]Specifying `disc3` causes `target` to be included in the kernel. ^[6]Specifying `scsi1` causes `sio`, `pfail`, and `pa` drivers to be included in the kernel.

Configuring HP-UX for a Magneto-Optical Disk

This section gives instructions on configuring HP-UX for a single magneto-optical disk. Configuring a single magneto-optical disk is done almost identically to configuring any hard disk to a single-ended SCSI interface card:

Select the device drivers from the table, Table 5-2 “Magneto-Optical Disk Configuration Requirements” in the previous section.
Follow the procedure, “Configuring HP-UX for a New Disk Device”, in Chapter 4 “Configuring Disk Drives, Disk Arrays, and CD-ROM Drives”
Unless you have purchased the disk preformatted, you may need to run mediainit to initialize the media. Refer to the hardware documentation or mediainit(1) in the HP-UX Reference.

If you are configuring an magneto-optical disk library, refer to the next section, “Magneto-Optical Disk Library Configuration Guidelines”.




	CAUTION: If you are configuring an existing 9.`x` magneto-optical disk to an HP-UX 10.0 system, be sure to read and follow the precautions detailed in the sections entitled “Planning to Configure into your System a Disk Already Containing Data ” and “Ensuring Against Clashes with HP-UX 10.0”, both located in Chapter 4 “Configuring Disk Drives, Disk Arrays, and CD-ROM Drives” of this manual.
