Operating Systems Solaris Disk or CDROM problem? Post 302399719 by asalman.qazi on Monday 1st of March 2010 10:09:11 AM

thanks for the reply incredible:

My question is:

1) if the cd/dvdrom drive is not being used can it generate such errors.

2) how is cd/dvd rom diffrentiated from normal hard drive in /dev file

in the above logs dvdrom is being shown as c0t0d0

now in unix same notation is being used for harddrives .
so how do we diffrentiate them.

3) if the cd/dvdrom is not being used by the system so will it do if we do not replace it and let it generate the errors in /var/adm/messages and truncate it periodically.

Thanks

wtmpconvert(8)						      System Manager's Manual						    wtmpconvert(8)

NAME
wtmpconvert - Modify connect time accounting records from DIGITAL UNIX releases 4.0x and prior to new format SYNOPSIS
/usr/lbin/wtmpconvert [-vnrp?h] input_file [output_file] OPTIONS
Restore new format to old format. Verbose. Display lines while converting. Do not preserve contents of input file. Formatted print only. Do not convert. (May be used with the -r option). Display usage message. DESCRIPTION
The wtmpconvert command reads records from a connect time accounting file, such as /var/adm/wtmp, and converts the record format to the updated struct utmp format. If no output file is specified or if the output file path is identical to the input file path, wtmpconvert makes a backup copy of the original input file using the following algorithm: If filename.orig exists. Where n is a unique number. The wtmpconvert command attempts to detect an input file that is in the wrong format (for example, input file is already a new format file). A warning message is issued in this case, but conversion continues. EXIT STATUS
Success. An error occurred. EXAMPLES
To convert an old format accounting file to the new format: wtmpconvert /var/adm/wtmp.prev Upon completion of this command, /var/adm/wtmp.prev will have been converted to the new format. The original /var/adm/wtmp.prev is renamed to /var/adm/wtmp.prev.orig. To convert a wtmp file in new format to the old format: wtmpconvert -r /var/adm/wtmp /var/adm/wtmp.old FILES
Accounting header files that define the format for the login database file. The active login/logoff database files. SEE ALSO
