Re: Attaching a real scsi device to a guest
I think there was some reasoning: all directory statements defining a device (MDISK, SPOOL, CONSOLE, SPECIAL, DEDICATE)) have the virtual address as the second word. But yes, then LINK is the exception. 2009/4/23 James Stracka (DHL US) james.stra...@dhl.com: I always say to myself we are defining Virtual devices so the first UCB is the virtual one on a DEDICATE, just as it is on an MDISK, GRAF or SPECIAL. Then IBM allows LINK which is backwards, but we all know that one! And, both UCBs are virtual, duh. It might have been helpful if between the two UCBs was the word USING. e.g. DEDICATE vucb USING rucb -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Rich Greenberg Sent: Thursday, April 23, 2009 8:24 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Attaching a real scsi device to a guest On: Thu, Apr 23, 2009 at 08:59:07AM -0400,Bauer, Bobby (NIH/CIT) [E] Wrote: } Oh nuts, I've got it backwards!

Attaching a real scsi device to a guest
We have been fortunate to obtain a small SAN device to play with in place of the 3390's that we are currently using to run z/VM and our Redhat Linux guest. I've been able to dynamically attach, configure a file system and mount it. The attach command went like: ATTACH to LSSB as 0900 I want to add this to USER DIRECT but a DEDICATE will not work and I don't see how MDISK will. Can somebody enlighten me?

Re: Attaching a real scsi device to a guest
I should have said 'does not work'.

Was just saying that it would have been easier to just have a copy of the error message you were getting (probably HCPATR040E Device 0900 does not exist) and someone would have probably poked you in the right direction straight away ! Just is/does/will not work(ing) is usually a bit too vague ! Anyway.. no big deal ;) --Ivan
