manual abstract
Once the option is selected, SCSISelect immediately scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the devices assigned to each ID. When you select a specific ID and device, a small menu appears, displaying the options Format Disk and Verify Disk Media. ¦ Format Disk—This utility allows you to perform a low-level format on a hard disk. Each hard disk must be low-level formatted before you can use your operating system’s partitioning and file preparation utilities, such as MS-DOS Fdisk and Format. Most SCSI disk devices are preformatted at the factory and do not need to be formatted again. The Adaptec Format Disk utility is compatible with the vast majority of SCSI disk drives. Cau t ion: A low-level format destroys all data on the drive. Be sure to back up your data before performing this operation. You cannot abort a low-level format once it is started. ¦ Verify Disk Media—This utility allows you to scan the media of a hard disk for defects. If the utility finds bad blocks on the media, it prompts you to reassign them; if you select yes, those blocks are reassigned to new blocks and will be available for use. You can press Esc at any time to abort the utility. Using SCSISelect and Disk Utilities SCSISelect Settings SCSI Bus Interface Definitions The following settings are the SCSISelect settings most likely to require any modification: ¦ Host Adapter SCSI ID— Sets the SCSI ID for the AAA-131U2/133U2. The AAA-131U2/133U2 is set to SCSI ID 7, which gives it the highest priority on the SCSI bus. We recommend you do not change this setting. ¦ SCSI Parity Checking—When set to Enabled, verifies the accuracy of data transfer on the SCSI bus. Leave this setting Enabled unless any SCSI device connected to the AAA-131U2/ 133U2 does not support SCSI parity. ¦ Host Adapter SCSI Termination—Sets the termination setting for each SCSI channel. We recommend that you leave the ULTRA2-LVD/SE connector setting for Channel A at Auto. For the remaining termination settings, leave them set to Enable unless the AAA-131U2/133U2 does not form one of the physical endpoints of the channel (the AAA-131U2/133U2 is not connected at the end of the internal cable). SCSI Device Configuration To configure settings for a specific SCSI device, you must know the SCSI ID assigned to that device (see Using the SCSI Disk Utilities on page A-4.) ¦ Initiate Sync Negotiation—When set to Yes, synchronous data transfer negotiation (Sync Negotiation) between the device and SCSI channel is initiated by the SCSI channel. Leave this setting set to Yes unless any SCSI device connected to the channel does not support Sync Negotiation. ¦ Maximum Sync Transfer Rate—Determines the maximum synchronous data transfer rate that the SCSI channel supports. For most SCSI devices, use the maximum rate supported. AAA-130U2 Series Installation and Hardware Guide ¦ Enable Disc...
