REXROTH VT-5006-17B設(shè)備探測(cè)功能每當(dāng)訪問指定設(shè)備時(shí)，都會(huì)進(jìn)行設(shè)備探測(cè)，并在設(shè)備描述符表中輸入條目；即，當(dāng)系統(tǒng)調(diào)用.DSKRD、.DSKWRREXROTH VT-5006-17BDSKFIGDSKFMT和.DSKTRL時(shí)，使用調(diào)試器命令BH、BO、IOC、IOP、IOT、MAR和MAW。設(shè)備探測(cè)機(jī)制利用SCSI命令“Inquiry”和“Mode Sense”。如果指定的控制器是非SCSI的，則探測(cè)只返回“設(shè)備存在且未知”的狀態(tài)。設(shè)備探測(cè)器使用相關(guān)數(shù)據(jù)在設(shè)備描述符表中創(chuàng)建一個(gè)條目。輸入后，下次進(jìn)行探測(cè)時(shí)，只需返回“設(shè)備存在”狀態(tài)（指向設(shè)備描述符的指針）。有關(guān)其使用的詳細(xì)說明，請(qǐng)參閱Motorola 68K CISC CPU調(diào)試包用戶手冊(cè)。向特定控制器LUN和設(shè)備LUN發(fā)出命令時(shí)，162Bug會(huì)記住這些LUN，以便下一個(gè)磁盤命令默認(rèn)使用相同的控制器和設(shè)備。REXROTH VT-5006-17B
Device Probe Function A device probe with entry into the device descriptor table is done whenever a specified device is accessed; i.eREXROTH VT-5006-17B when system calls .DSKRD, .DSKWR, .DSKCFIG, .DSKFMT, and .DSKCTRL, and debugger commands BH, BO, IOC, IOP, IOT, MAR, and MAW are used. The device probe mechanism utilizes the SCSI commands “Inquiry” and “Mode Sense.” If the specified controller is non-SCSI, the probe simply returns a status of “device present and unknown”. The device probe makes an entry into the device descriptor table with the pertinent data. After an entry has been made, the next time a probe is done it simply returns with “device present” status (pointer to the device descriptor).Disk I/O via 162Bug Commands These following 162Bug commands are provided for disk I/O. Detailed instructions for their use are found in the Debugging Package for Motorola 68K CISC CPUs User’s Manual. When a command is issued to a particular controller LUN and device LUN, these LUNs are remembered by 162Bug so that the next disk command defaults to use the same controller and device.REXROTH VT-5006-17B
