disk

Command 

Lists all of the system's drives. Also lets you choose the disk you want to use in subsequent operations. This disk is referred to as the current disk. 

type

Command 

Identifies the manufacturer and model of the current disk. Also displays a list of known drive types. Choose the Auto configure option for all SCSI-2 disk drives.

partition

Menu 

Creates and modifies slices. For more information, see The partition Menu.

current

Command 

Displays the following information about the current disk: 

• Device name and device type

• Number of cylinders, alternate cylinders, heads and sectors

• Physical device name

format

Command 

Formats the current disk by using one of these sources of information in this order: 

1. Information that is found in the format.dat file

2. Information from the automatic configuration process

3. Information that you enter at the prompt if there is no format.dat entry

This command does not apply to IDE disks. IDE disks are pre–formatted by the manufacturer. 

fdisk

x86 platform only: Runs the fdisk program to create a Solaris fdisk partition.

repair

Command 

Repairs a specific block on the current disk. 

label

Command 

Writes a new label to the current disk. 

analyze

Menu 

Runs read, write, compare tests. For more information, see The analyze Menu.

defect

verify

Command 

Prints the following information about the current disk: 

• Device name and device type

Create a partition

Creates an fdisk partition. You must create a separate partition for each operating system such as Solaris or DOS. There is a maximum of 4 partitions per disk. You are prompted for the size of the fdisk partition as a percentage of the disk.

Change Active partition

Lets you specify the partition to be used for booting. This menu item identifies where the first stage boot program looks for the second stage boot program. 

Delete a partition

Deletes a previously created partition. This command destroys all the data in the partition. 

Exit

Writes a new version of the partition table and exits the fdisk menu.

Cancel

Exits the fdisk menu without modifying the partition table.

    read     - read only test   (doesn't harm SunOS)
    refresh  - read then write  (doesn't harm data)
    test     - pattern testing  (doesn't harm data)
    write    - write then read      (corrupts data)
    compare  - write, read, compare (corrupts data)
    purge    - write, read, write   (corrupts data)
    verify   - write entire disk, then verify (corrupts data)
    print    - display data buffer
    setup    - set analysis parameters
    config   - show analysis parameters
    quit
analyze> 

read

Reads each sector on the current disk. Repairs defective blocks as a default. 

refresh

Reads then writes data on the current disk without harming the data. Repairs defective blocks as a default. 

test

Writes a set of patterns to the disk without harming the data. Repairs defective blocks as a default. 

write

Writes a set of patterns to the disk then reads the data on the disk back. Destroys existing data on the disk. Repairs defective blocks as a default. 

compare

Writes a set of patterns to the disk, reads the data back, and then compares it to the data in the write buffer. Destroys existing data on the disk. Repairs defective blocks as a default. 

purge

Removes all data from the disk so that the data can't be retrieved by any means. Data is removed by writing three distinct patterns over the entire disk (or a section of the disk). If the verification passes, a hex-bit pattern is written over the entire disk (or a section of the disk). 

Repairs defective blocks as a default. 

verify

Writes unique data to each block on the entire disk in the first pass. Reads and verifies the data in the next pass. Destroys existing data on the disk. Repairs defective blocks as a default. 

print

Displays the data in the read/write buffer. 

setup

Lets you specify the following analysis parameters: 

Analyze entire disk? yes
Starting block number: depends on drive
Ending block number: depends on drive
Loop continuously? no
Number of passes: 2
	Repair defective blocks? yes
Stop after first error? no
Use random bit patterns? no
Number of blocks per transfer: 126 (0/n/nn)
Verify media after formatting? yes
Enable extended messages? no
Restore defect list? yes
Restore disk label? yes

Defaults are shown in bold. 

config

Displays the current analysis parameters. 

quit

Displays the in-memory defect list.
