Name

rx − RX33/RX23 Small VAX floppy disk drive

Description

The RX33 floppy disk drive, when used by either the workstation or multiuser configurations of the busless Small VAX processor, is supported by the SDC disk driver.  The SDC disk driver also supports the RX23 floppy disk drive in VAXstation 3100 Model 30 systems.  The SDC driver handles the RX33/RX23 disk on drive 2. 

The RX33 floppy disk drive reads and writes both RX33 and RX50 floppy diskettes.  The RX23 floppy disk drive reads and writes high density (18 sectors per track) RX23 floppy diskettes and reads double density (9 sectors per track) RX23 floppy diskettes. 

Formatting RX23 Floppy Diskettes (VAXstation 3100 Model 30 Only)

The floppy diskettes used with the RX23 floppy disk drive are not always preformatted.  Although the ULTRIX system does not currently include support for online formatting of diskettes, the VAXstation 3100 diagnostic t 70 command allows you to format diskettes. 

Use the following steps to format diskettes:

1.Shut down the ULTRIX Worksystem Software, and halt the processor. 

# /etc/shutdown −h +5

2.Insert the diskette into the RX23 drive. 

3.Enter the following at the prompt:

>>> t 70
 

The t 70 command begins to prompt you for information. Answer each query as in the following example. Press the RETURN key after each response:

     KA42 RDRXfmt
 VSfmt_QUE_unitno (0-3) ? 2
 VSfmt_QUE_RXmedtyp
 ( 1=RX33 ),( 2=RX23 ) ? 2
 VSfmt_QUE_RUsure (DUA2 1/0)  ? 1
 VSfmt_STS_FMTing ..... OK
 VSfmt_STS_CKRXfmt .....OK
 VSfmt_RES_Succ
