well 9 tape drives sit in one zone with an HBA, but those same 9 drives sit in another zone with a storage node, and 5 of those drives then sit in yet another zone with a NAS head, but Legato controls all communications to the drives, so it should control access.
Maybe there is some sort of problem with sharing drives in NDMP backups, but the problems happen long after NDMP operations are over. thanks for your feedback on this -----Original Message----- From: [EMAIL PROTECTED] on behalf of Darren Dunham Sent: Thu 10/13/2005 7:22 PM To: [email protected] Subject: Re: [Solaris-Users] st.conf entry question > each HBA is zoned in with 9 lto2 drives > > each zone has only one initiator > > we are using an sl8500 silo, and acsls to control the silo > > all the drives show up, but I'm not sure if that many drives per hba > is supported I don't see a problem with it per se, but you can't actually push all 9 at full speed over one 2Gb/s link.

If those drives are in only one zone, then that certainly eliminates many different possibilities (like another host sending a spurious reset). Tracking down fiber errors is never fun. Sysadmin tools aren't very good at that level. Make sure all the drives and switches are at recommended firmware levels. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
