- scsidiskformat is a utility for the low level format of devices accessed
- using the _S_G_I _S_C_S_I subsystem. It sends a 6 byte FFFFoooorrrrmmmmaaaatttt UUUUnnnniiiitttt command to
- the device.

- Decides whether the Format Unit Parameter list [defect list header +

- _1 the list is supplied to the device.

- Decides whether the device performs a verify function during format.
- When set to _1 the device does not perform a verify function during
- formatting (thus no C list for this format is created or

- The Format Unit command can also be used to modify the number of user

- ----DDDD Non-interactive mode to format a device with optimum format
- settings. In this mode, the settings are as follows : FMT DATA =
- 1, CMP LST = 0, FOV = 1, DPRY = 0, DCRT = 0, STPF = 1, IP = 0, Immed
- = 0.
-
- It is recommended to use the above format settings unless there is
- sufficient justification to change them.
-
-
- ----GGGG Non-interactive mode option to purge the previous Growth(G),
- Certification(C) Defect Lists from the device. This option sets the
- CMP LST Bit to 1.
-
-
- ----CCCC Non-interactive mode option to set the DCRT (Disable Certification
- Bit) to 1. When the DCRT bit is set to 1, the device doesnot perform
- a Verify Function during formatting (thus no C list for this format
- is created or reallocated).
-
-
- ----SSSS Non-interactive mode option to set the STPF (Stop Format) bit to 0.
- When the STPF bit is set to 0, formatting is not terminated if an
- error is encountered while accessing either the P or G defect lists.

- scsidiskformat is invoked with the ----dddd _D_e_v_i_c_e option. The Device must
- correspond to the 'sc' device. For example
-
- ssssccccssssiiiiddddiiiisssskkkkffffoooorrrrmmmmaaaatttt ----DDDD ----dddd ////ddddeeeevvvv////ssssccccssssiiii////sssscccc9999dddd77770000llll0000
-
- As a general rule using the ----DDDD (Optimum Settings option) will result in
- the best results. Change the optimum settings, only if you are fully
- aware of the changes they make to the SCSI or Fibre Channel device.
-
-
- In the interactive mode an invalid choice results in the default option
- (specified in []) being chosen. For example
-
- SSSSeeeetttt DDDDPPPPRRRRYYYY ((((DDDDiiiissssaaaabbbblllleeee PPPPRRRRiiiimmmmaaaarrrrYYYY)))) BBBBiiiitttt???? ((((yyyy////nnnn))))
-
- Any keystroke other than 'y' or 'Y' will result in 'n' being chosen.
- This facility ensures that the best choices (set as default) are always
- chosen unless the user wishes otherwise.
