Subject: "ata73" == "sd 72" ?
Date: Thu, 17 Apr 2008 20:30:12 -0400 [thread overview]
Message-ID: <4807EB94.80104@rtr.ca> (raw)
While working on sata_mv today, I noticed something weird in the syslog.
The messages from libata show "ata73" for the port with my drives (pmp),
but the messages from SCSI (sd) show "sd 72" for those same drives.
One would really think that these two numbers should agree,
not be off by one. I wonder why they differ (or why they are
almost the same) ?
