Hi Folks, We are having these errors with another type of drive as well - it seems to be related to trying to read the tape after a move operation. Using a single CPU kernel did not affect the problem... (ch0:ahc0:0:0:1): MOVE MEDIUM. CDB: a5 20 0 0 0 3 0 1 0 0 0 0 (ch0:ahc0:0:0:1): ILLEGAL REQUEST asc:3b,d (ch0:ahc0:0:0:1): Medium destination element full ch: warning: could not map element source address 0d to a valid element type (sa0:ahc0:0:0:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM command t o clear this state.

System description: System 4.2 stable (cvsup 12/10/00) (4.2-STABLE FreeBSD 4.2-STABLE #3:) Dual 266mhz PII, PB2-D ASUS MB, Adaptec 2930CU card Overland 4000 DLT tape library (LXS4115) or HP SURESTORE 1200 DDS2 . Any insights to a solution would be appreciated. thanks, hurf Hurf Sheldon wrote: > > Hi Folks, > We are getting "Queuing a BDR SCB" errors and then related > problems trying to access a DLT tape library via `amlabel` > or `chio` (which `amlabel` uses).
