corrupt block

[Dagmar Bendová]

Hallo,
Our system is running at OS HP-UX 11.00. Does any utility exist that can found out a corrupt block at disk? I need an utility that can work with raw devices. I tried stm. I can not understand the output file - raw file. There is an error - EIO 5 and description of the mistake is in hexadecimal mode.
Thanks Dadie

Hi,

Diffecult, you could try

# dd if=/dev/rdsk/cxtydz of=dev/null bs=1024

I'm not shore it will report the exact block.

Hope this helps,

Hi

U can always check thru' dd.

dd if= of=/dev/null

U have to get input and output as same.

if any mismatch u can conclude the bad blocks.

Hope this will help you.

I have tried cmd dd with this result:
dd read error: Unknown error
1466160+0 records in
1466160+0 records out

Hi Dadie,

Could you check the output from,

# diskinfo -v /dev/rdsk/cxtydz

and check if the number of block correspond to the number of blocks from your dd command.

Hi dadie,

there is a utility inside stm called the logtool which is used to read the raw logs created stm. execute stm and invoke the logtool utility and specify the location of the raw log file corresponding to your disk. This utility will convert the raw log file into a readable format and will be displayed on the screen.

but as robert said, dd is also a good util to check up the consistency of your disk

With best wishes

Thanks for your answer but I can not understand raw file. Commands dd has finished at I/O error and I don´t know if it is hardware problem or software problem. How can I recognize it? Can command mediainit solve this problem? What I have to do whith this disk?
Thanks, Dad
