Requirement Form[Informati1]
Date: 08/29/2006 Requirement #: WAVV200707
Title: (Paraphrase problem in a single statement)Provide and document IUCV
system service for interacting with channel-attached tape libraries
Detailed Problem Description: (Description of what you want changed - 400 character entry limit)
Provide a documented
interface to allow native systems and guests (particularly Linux) to manipulate
channel-attached tape libraries without requiring library partitioning or
device conversion to SCSI.
Priority:
(Select one:
Urgent - High - Medium - Low) High
Requested Completion Date: (When?
Examples: 3 months, 1 year, Next Release) Next Release
Requirement Type: (Select one: Acceptability - Compatibility/Migration - Ease of Use - Feature/Function - Performance - Reliability/Availability/Serviceability - Packaging - Interoperability)
Feature/Function
Business Justification: (Why? Non-technical business case description. Do not reword Detailed Problem Description from above. What are the benefits to be gained by your company, and the vendor and others? Quantify: run time, dollars, manpower, etc. Why should the vendor do this for the customer?)
Currently, there is no
documented interface to the library controller modules in channel attached
libraries that is accessible from Linux. The IP interface currently provided in
DFSMS/VM is incomplete and unreliable, and does not permit convenient
manipulation of devices without partitioning the library. These devices
represent substantial investments and are not likely to be replaced to
accomodate SCSI-based commands currently understood by Linux. Enabling these systems to have a common
control interface that does not reveal the specifics of the channel protocol
for the library (and does not require APPC) is necessary to allow Linux to
leverage these devices effectively.
Solution: (Optional)(Desired/undesired elements Note: Making a suggestion may limit a vendors ability to deliver a solution)
A desired element would be to
present the changer as a CP-managed system service, preferably one that could
also accept SCSI command words such as produced by the mtx utility and
translate those words to the equivalent channel-attached library
functions/commands.
Impact: (Optional) (How will your company’s business be affected if a solution is not delivered?)
Further argument to remove
the mainframe and replace with "more compatible" device.
