Flag Description<br />

-t Format Lists each string preceded by its offset from the start of the file. The<br />

format is dependent on the character used as the format variable:<br />

5.9.5 The sysdumpdev command<br />

d writes the offset in decimal.<br />

o writes the offset in octal.<br />

x writes the offset in hexadecimal.<br />

When the -o and the -t Format flags are defined more than once on a<br />

command line, the last flag specified controls the behavior of the<br />

strings command.<br />

-Number Specifies a minimum string length other than the default of four<br />

characters. The maximum value of a string length is 4096. This flag is<br />

identical to the -n Number flag.<br />

File Binary or object file to be searched.<br />

The sysdumpdev command changes the primary or secondary dump device<br />

designation in a system that is running. The primary and secondary dump<br />

devices are designated in a system configuration object. The new device<br />

designations are in effect until the sysdumpdev command is run again, or the<br />

system is restarted.<br />

If no flags are used with the sysdumpdev command, the dump devices defined in<br />

the SWservAt ODM object class are used. The default primary dump device is<br />

/dev/hd6. The default secondary dump device is /dev/sysdumpnull.<br />

Note: Do not use a mirrored or copied logical volume as the active primary<br />

dump device. System dump error messages will not be displayed, and any<br />

subsequent dumps to a mirrored logical volume will fail.<br />

Do not use a diskette drive as your dump device.<br />

If you use a paging device, only use hd6, the primary paging device. <strong>AIX</strong><br />

Version 4.2.1 or later supports using any paging device in the root volume<br />

group (rootvg) as the secondary dump device.<br />

The sysdumpdev command syntax is as follows:<br />

sysdumpdev [-c | -C] -P { -p Device | -s Device } [ -q ]<br />

sysdumpdev [-c | -C] [ -p Device | -s Device] [ -q ]<br />

sysdumpdev [-c | -C] [ -d Directory | -D Directory | -e | [ -k | -K ] | -l | -L<br />

| -p Device | -q | -r Host: Path | -s Device | -z ]<br />
