In Fig. 1-3, do you mean TS3500 rather than TS3350?

On page 305 I believe you intended to reference multiple OS's (rather than just z/VSE) in the statement about restrictions. I'm assuming it was z/VM?
========================================
Restrictions in all TS7700 Virtualization Engine environments
Neither z/VSE are able to provide SMS constructs to TS7700. Therefore, the functions
provided by outboard policy management for the TS7700 Virtualization Engine cannot be
used on these platforms.

Also on page 305 I believe it was intended to have "z/VSE" in between "the" and "and" in the last sentence:
=========================================
Additional
information about third-party tape management systems that support the TS7700
Virtualization Engine in the and z/VM environment can be found in IBM TotalStorage 3494

on page 145 you reference
"z/OS DFSMSrmm Implantation and Customization Guide,SC26-7405"
this definitely should be
z/OS DFSMSrmm Implementation and Customization Guide

Hi,
The book contains references to GDPS with TS7700.
Is the TS7700 family officially/non-officially suported by GDPS ?
It seems to me that some restrictions regarding GDPS and TS7700 mentioned in the book, are no longer necessary.
My reasoning is that TS7700 provides disaster recovery options
that almost nulified the previous (3494-B20) requirements.
I would appriciate your opinion, thanks,
Arye Shemer.

There is nothing we do that prevents a client from using GDPS, but GDPS does not yet officially supported the TS7700. There are a series of functions we currently provide that GDPS will leverage to help do the following:

1. Isolate a cluster with respect to inbound/outboud replication.
2. Provide a count of volumes which are not yet replicated to a cluster.
3. Provide a list of volumes which are not yet replicated to a cluster.

All of these three functions can be carried out today. GDPS is simply going to put a GDPS front end in to help automate the process. GDPS has struggled to find the time and hardware to test the support of these TS7700 functions. I believe it may be occurring soon as the issue has gotten more attention recently.
