Disk scan command

Dan DeHaan — Tue, 21 Dec 2004 13:53:25 GMT

A year or so ago, I came across a command to check the status of UPUX harddrives. It wasn't checking the filesystem, but the actual physical health of the drive. Now I need it, but can't find or remember it. Any ideas?

Hi Dan,

Something like a read test ?

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

No, something more like checking bad sectors and stuff like that.

Hi Dan,

TAKE VERY GOOD CARE WITH THE MEDIAINIT COMMAND!

Are you looking to display stale extends in a logical volume like the question you had in below thread ?

No. In that thread I even mention that we tested the drives. The command I'm looking for was the command we tested with. I wrote it down somewhere safe, but now, well ....

diskinfo -v /dev/rdsk/cxtydz

# cstm
cstm>map
cstm>sel dev
cstm>info
cstm>infolog

there is a tool from seagate but not for HPUX.

The more I get thinking about it, the more I believe it was the mediainit command. Thanks for your help guys.
