86 Software Installation and User’s Guide
Installing SCO OpenServer
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.
