Supported hosts
This section describes hosts supported by the IBM® TS7700.
The TS7700 supports the following host attachments:
- IBM Z® mainframe
- IBM s390 server
The TS7700 supports the following operating systems:
- z/OS®, V1R13 and later (earlier release levels were initially supported, however those release levels are no longer in service. Refer to Preventive Service Planning bucket D/T3957 from the IBM Support and Downloads link in the Related information section for the list of applicable maintenance)
- z/VM®, V5.4.0 and later. V5.4.0 or later with the PTFs for APAR VM64979 is required for both guest and native VM support providing base CP functions.
- z/VSE®, 4.3 and later. With z/VSE, the TS7700 is transparent to host software. z/VSE supports the TS7700 as a stand-alone system in transparency mode. z/VSE 5.1 or later supports copy export and a multi-cluster grid.
- zTPF, V1.1 and later. With z/TPF the TS7700 is supported in both a single node and a grid environment with the appropriate software maintenance. The category reserve and release functions are not supported by the TS7700.
Notelist:
- Native VM Tape library support for these drives is provided by DFSMS/VM FL221 with PTFs for RMS APAR VM64773 and VM65005 and their prerequisite service.
- EREP V3.5 plus PTFs is required.
Supported
hosts connect to the TS7700,
which connects to a TS3500 or
TS4500 Tape Library, either directly or through a 3953 L05 Library Manager.
Note: Attachment to a TS3500 Tape Library via a 3953 L05 Library Manager is only supported by TS7740
microcode levels prior to 8.5.0.xx. Attachment to a TS3500 Tape Library without a 3953 L05 Library Manager is supported by TS7740
microcode level 8.5.0.xx or later.
A host connects to the TS7700 via the 8 Gb or 16 Gb FICON® adapters. Each installed adapter supports 512 virtual paths.
- Control Paths
- A control path is a virtual path into the virtual library along which a host sends control commands. Each tape drive that is attached to a subsystem can act as a control path. A 3592 Tape Drive must be designated as a control path if 3592 Tape Drives are to operate successfully in a TS3500 Tape Library attached to the TS7700.
