The files

 list the devices found 

during boot up of Open Server. The current SCSI controllers can be found 

using the command:

This command produces output similar to:

%adapter  0x6400–0x64FF     11 type=alad ha=0
bus=0  id=7  fts=st0.

The current tape drives can be found using the command: 

We suggest using the AIX commands

and

when transferring data to and from the LTO-2 Half-

Height Tape Drive. These commands transfer data more 

quickly than other commands such as tar and cpio.
• For cpio we suggest a blocking factor of 128. 
• For tar we suggest using the .N option and a factor of 

128.

•  Some older systems with poor video controllers may 

experience a reduction in performance when using 

the .v option, which prints the path names on the 

standard console during the backup. Unless there is a 

real need to see the filenames as they are backed up we 

suggest not using the .v option. 

• For commands that use density and tape size settings 

the tape density is 124,000 bpi and the tape length is 

1800 feet.
