— Provide a common Lock Name for each tape drive. To enable shared
access of tape drives by different hosts, you must use the same Lock
Name for each instance of the same tape drive. In this example, drives
“lpc7060_drive_1” and “lpc7062_drive_1” are configured with the
same Lock Name, “drive_1”.
— Verify that SCSI Reserve/Release is NOT checked. This feature is
meant to be used in place of the Lock Name or in conjunction with
other software applications sharing the same tape libraries. Multiple
applications on the same SAN are not supported. In addition, if an
error occurs accessing a tape drive, the drive may be left reserved by
the host and, therefore, unavailable from other servers. Once a tape
drive is left reserved, manual intervention is required to release it.
— Verify that Use direct library access is NOT checked. This feature
allows each host on the SAN to access the robotics directly. This is not
supported. For higher available access to the robotics controller, the cell
server and control of the tape library may be configured on a clustered
server.
