The FE replaced the High speed disk drive but was having trouble with cd rom drive during the software load. cd rom daigs fail with 00 instead of 30761 10 /tmp/CDROMtest for the TEAC cd rom Since the CDROM Drive is seldom used except for loading system software, it is advisable at this time to perform a quick test on the ability of the CDROM drive to read data from a CD before you begin the LFC procedure. This test is accomplished by inserting and mounting one of the OS CDROM disks, and performing a checksum (read check) on the files in one of the directories on the CD. If any errors occur while the system is reading this CDROM, you must stop to investigate and correct the CD problem (for example the SCSI Bus, CDROM Drive, etc. problems). 1.) Open a UNIX shell. 2.) Type: tail -f /usr/adm/SYSLOG <ENTER> 3.) Open a second UNIX shell. 4.) Insert the IRIX 6.2 OS CD-ROM (2282439-2) into the CDROM Drive and type: mountCD /mnt <ENTER> cd /mnt/dist <ENTER> sum * > /tmp/CDROMtest <ENTER> (~5 minutes to display prompt) 5.) While the system is reading the CDROM and calculating checksums, you need to monitor the SYSLOG in the first UNIX shell window for any error messages that may occur that are related to SCSI or CDROM problems (timeouts, read errors, SCSI Bus resets, etc.). 6.) If checks are successful (no errors produced), type the following command to verify the checksum: sum /tmp/CDROMtest <ENTER> 7.) Verify that the resultant display for the command in step 6 is: 30761 10 /tmp/CDROMtest but the TEAC drive responded with 00 8.) If you encounter any CDROM or SCSI related errors during this check, stop and troubleshoot/ repair the problem before attempting to perform the FMI. 9.) Terminate the 'tail' command by typing ^C in the first UNIX shell window where the 'tail' command is running. 10.) Unmount the CDROM by typing the following commands in the second UNIX shell window: cd / <ENTER> unmountCD <ENTER>
