DISKSCAN(1M) Maintenance Commands DISKSCAN(1M)


NAME


diskscan - perform surface analysis

SYNOPSIS


diskscan [-W] [-n] [-y] raw_device


DESCRIPTION


diskscan is used by the system administrator to perform surface analysis
on a portion of a hard disk. The disk portion may be a raw partition or
slice; it is identified using its raw device name. By default, the
specified portion of the disk is read (non-destructive) and errors
reported on standard error. In addition, a progress report is printed on
standard out. The list of bad blocks should be saved in a file and later
fed into addbadsec(1M), which will remap them.

OPTIONS


The following options are supported:

-n
Causes diskscan to suppress linefeeds when printing progress
information on standard out.


-W
Causes diskscan to perform write and read surface analysis. This
type of surface analysis is destructive and should be invoked with
caution.


-y
Causes diskscan to suppress the warning regarding destruction of
existing data that is issued when -W is used.


OPERANDS


The following operands are supported:

raw_device
The address of the disk drive (see FILES).


FILES


The raw device should be /dev/rdsk/c?[t?]d?[ps]?. See disks(1M) for an
explanation of SCSI and IDE device naming conventions.

NOTES


The format(1M) utility is available to format, label, analyze, and repair
SCSI disks. This utility is included with the diskscan, addbadsec(1M),
fdisk(1M), and fmthard(1M) commands available for x86. To format an IDE
disk, use the DOS format utility; however, to label, analyze, or repair
IDE disks on x86 systems, use the Solaris format(1M) utility.
