    Hello,

    I have the following configuration for backup:

    - Solaris 8 with latest st.conf patch 108725-17
    - NEO 2000 tape library with SDLT320 and SDLT600
    - Software Veritas Netbackup V5.1 MP1
    - st.conf for SLT600
    tape-config-list=
    "QUANTUM SDLT600", "QuantumSDLT", "SDLT_data";
    SDLT_data = 1,0x38,0,0x19639,4,0x00,0x00,0x00,0x00,3;

    If the backup software is mounting a tape on the SDLT600 drive I got the
    following message logs in /var/adm/logs

    bptm[3540]: [ID 832037 daemon.error] scsi command failed, may be
    timeout, scsi_pkt.us_reason = 20

    which means according to the /usr/include/sys/scsi/scsi_pkt.h

    #define CMD_UNX_BUS_FREE 20 /* Unexpected Bus Free Phase
    occurred */

    that an unexpected bus free phasee error occured.

    I already replaced the SDLT600 tape by a new one but the error still
    comming up. Therefore I assume no hardware error. The library and
    SDLT320 are on the same scsi bus and with SDLT320 there are no problems.

    The NEO2000 are at a new SUN Ultra-2 PCI adapter with qus driver, I
    installed because this in not part of Solaris 8 or 9.

    I discussed this already with Veritas but no solution comes up since
    within the last 4 weeks.

    Can anybody help me or give some hints about this error behavior ?

    I will summarite.

    Thanks a lot in advance,

    Anton
