New or Modified SMF Record Formats
ELS 7.2 includes the following new or modified SMF Record formats:
These updates supersede the information found in the ELS Programming Reference, Chapter 5, SMF Record Formats.
VTCS SMF Subtype 11 Record (SLSSMF11)
The VTCS SMF subtype 11 record format is updated:
- New VSM6 interface types are added to reflect each type of VSM6 interface. Under field SMF11TOL, the following new equates are added:
- X'0003', SMF11V6H, VSM6 HOST INTERFACE
- X'0004', SMF11V6R, VSM6 RTD INTERFACE
- X'0005', SMF11V6I, VSM6 IP INTERFACE
- Under field SMF11CSP, the following equate is added under field SMF11CSP to indicate VSM6 FICON channel speed:
- X'8000', SMF11V6F, VSM6 FICON CHANNEL
- Fields SMF11NIO and SMF11CUB have been redefined and documented to provide more meaningful statistics for VSM6 storage systems.
The complete and updated table for VTCS SMF subtype 11 record format is:

Note:
The Tapeplex name field can be found in the SMF record after the repeating sections. It has been defined as part of the fixed area to allow it to be accessed using its name when the total length of the variable area is added to the starting address of the SMF record.
