Configuring for Linux

13When the process takes you back to the two Main Menu screens, press q.

14When asked to create a new kernel, enter yes.

15When asked if you want the new kernel to boot by default press y.

Note: Not all of the SCO “tape” commands will operate or be applicable to the LTO-3 Tape Drive (execute the command

.man tape. for the specifics on how the tape command works). The following tape commands are not available for use with the LTO-3 Tape Drive: getcomp, setcomp (the LTO-3 Tape Drive will always compress the data before writing the data to tape under SCO Open Server 5.0.x), partition, setpart, getpart, getspeed, setspeed, rsm, wsm. The following tape commands are available for use with the LTO-3 Tape Drive: status, load, reset, rewind, retention, getblk, setblk, unload, eod.

When using the GUI Backup Manager utility set the block size to 32768 minimum, 65536 preferred. When using commands such as tar we suggest using the tape command to set the block size to 512 and then using a blocking factor of 80 for the tar command. For commands that use density and tape size settings the tape density is 124,000 bpi and the tape length is 1800 feet.
