— 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 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.
