Ok, and since I am directly attached to the array thusly:
HBA1->SPA HBA2->SPB with the luns configured in: a,b,a,b,a,b type of LUN ownership, the ASL/APM and DMP are doing their job accordingly. Does this make the 'format' command output more of an aesthetic 'issue'. A red herring, in other words? -James ----- Original Message ---- From: Darren Dunham <[EMAIL PROTECTED]> To: Veritas-vx@mailman.eng.auburn.edu Sent: Tuesday, September 4, 2007 2:09:48 PM Subject: Re: [Veritas-vx] Drive type unknown Solaris 10 > HBA1 -> SW1 -> SPA (primary) > HBA1 -> SW1 -> SPB (failover) > HBA2 -> SW2 -> SPA (primary) > HBA2 -> SW2 -> SPB (failover) > > In explicit failover mode you can do some "base" operations to the LUN > on the failover interface (such as answer a SCSI INQUIRY command) but > more complex operations (such as real I/O) will fail until a special > "bring it over here" command is sent (this would be an explicit > request to failover the LUN -- thus "explicit failover").

Since the logic of this is in the ASL/APM and available only to VxVM, 'format' and the lower layers don't get the benefit. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
