5.1 Load Software Update(s) from SCANS
OVERVIEW
Note: It is recommended that the host 5E and all subtending DRMs be maintained
at the same or within 1 SU/BWM level of each other, with only 2 SU/BWM levels
across all nodes. The Host 5E should always be updated first before updating any
DRMs.
If the host and subtending DRMs become more than 1 SU/BWM level apart or at least
1 DRM is at a higher SU/BWM level than the host 5E, the following will occur:
1. The application of a new SU/BWM on the 5E will be blocked. If this cannot be
corrected by updating the SU level on the DRM(s), the following command can
be entered at a 3B21 unix prompt to override the check that blocks the SU
application:
touch /etc/.NO2LVLCHECK
2. The following output message may be generated on the ROP when accessing
Recent Change & Verify (RCV) for a DRM via the ASM:
*REPT ASM VTTY ASM SERVICE rc NOT AVAILABLE, USING AM SERVICE
INSTEAD
This message indicates that layer 1 and 2 RCV crosschecks will be performed
locally on the DRM rather than on the ASM. This will result in a slight decrease
in RCV throughput but will not block the ability to perform RCV.
Once an SU has been sent to the /etc/bwm directory using the following procedure,
the SU can be applied by using either a cut-through to the Host and each DRM and
manually applying the SU from the 1990 MCC page or by using SU Automation
(section 2.12.6.2) to automatically apply the SU to the Host and all DRMs in the
Switching Complex The SU Automation method can only be used when an SU is to be
installed on the Host and all the DRMs in the complex together. If SU installation on
only the Host or a subset of DRMs is desired, then it must be done via a cut-through
to each Host/DRM’s MCC.
The DRM and host can be in different stages of BWM installation.
Note: This procedure should only be used if

Software Updates.”
This procedure can be performed via the ASM or at a DRM site.
In order to load a software update using the Software Change Administration and
Notification System (SCANS), a terminal and dial-up modem are needed along with a
SCANS login. When the SCANS login is obtained, the SCANS User’s Guide and the
Training Manual are also provided.
SCANS provides menu driven access to informational bulletins and software updates
(SUs). The basic process of loading an overwrite from SCANS is as follows:
•
Set up the AW to receive an SU from SCANS.
•
Log in to the SCANS system and request the software update.
