Hmm??? If a tape hasn't been mounted yet, i.e. read or accessed, it's quite possible that paramaters aren't known, are they? The purpose of the .ctl device is mostly to be able to access the device when somebody has the regular device open. The man page may need updating. What do you mean by 'persistent' parameters? Held across multiple mount sessions, or permanent across reboots? > At the moment I'm just saying "%#@! it", since my storage manager resets > the block size anyhow within a session (so non-persistence doesn't affect > my backup software anyhow)... but that doesn't solve the problem of me > being curious :-}. Did you unmount the tape? That will probably clear things. Sounds like an RFE is in the works here. Jeez, between you and Jean-Francois, it looks like I'll really have to fix things I've been putting off. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
