Installing SCO OpenServer Table 8-6. UNIX Target ID and LUN HA Bus Target ID 0 0 0 0 0 2 0 1 3 1 0 0 1 0 1 1 0 2 1 0 3 LUN Device 0 1st Hard Disk, host drive no. 0 (boot drive) 0 Streamer 0 CD-ROM 0 Hard Disk, host drive no. 0 0 Hard Disk, host drive no. 1 0 DAT 0 Hard Disk, host drive no.2 Caution: Non-Direct Access Devices must not be connected to Bus 0, Target ID 0, LUN 0. This is reserved for the boot device under OpenServer. 8.3 Additional Information • From version 4.x of OpenServer, a media change can be made with the UNIX commands MOUNT and UNMOUNT. Ensure that the removable hard disk keeps its ICPCON drive number when changing the media, otherwise a separate ID/LUN entry is necessary for each single media (since the drive number depends on the media and not the device containing it). • OpenServer and later versions support a maximum of 4 ICP RAID controllers in one computer system. • The tool RAIDSYNC in the directory '/etc' carries out a UNIX SYNC command (update super block) and causes all buffers still present in ICP RAID controller's cache to be written to the logical drives. It is advisable to use this tool before shutting down the system. • When using Direct Access Devices with exchangeable media (for example, removable hard disks), a media has to be inserted when the system is booted, otherwise the device is not available under UNIX. • Non-Direct Access Devices (streamer, tapes, CD-ROMs, etc) can be switched on even after system power up. They will still be recognized by SRCSCAN. 8.4 Remote Monitoring with the SRCD Remote Access Service srcd is the remote access service for IIR controllers. With srcd running, you can manage disk arrays from a remote workstation using storage management software (for example, StorCon) via TCP/IP. 86 Software Installation and User's Guide
