A5.5.1 Full Backup of Office
1. Execute procedure 6.17 from the 235-105-210 Switch Routine Operations and
Maintenance Procedures
2. It is recommended that a full set of office backup tapes be created just prior to
the conversion. These may consist of one multi-volume backup tape for some
releases. Refer to the 235-105-210, 5ESS®-2000 Switch Routine Operations and
Maintenance Procedures, “Make Full Office Backup Tape”, Section 6.23.
Automated System Backup can also be used by following Section 6.41, "Schedule
Backup To Tape Using Automated System Backup Feature."
These tapes are only needed in the case that both Netra 20 disks would become
corrupted, and it would become necessary to fall back to the Netra t 1120
workstation. To deadstart an office from tape: refer to the DRM User’s Guide,
Chapter 7, "System Recovery."
3. Be sure to include a backup of the Operating System and Emulator to tape. For
the procedure to create a backup tape. Refer to the DRM User’s Guide, Section
4.4, "Back Up Administrative Workstation Operating System."
A5.5.2 Restore MHDs on AW
1. At the AM, AM Peripherals page, type and enter command 111.
2. Are any of the MHDs Out Of Service (OOS)?
If YES, continue.
If NO, no further action is required.
3. Enter the appropriate pokes to restore all OOS MHDs. Type and enter command
30X:
Where: X = MHD number that is OOS.
Response: RST MHD x IN PROGRESS
Where: X = is the first MHD restoral requested; the other will be
restored when the first is completed.
A5.6 Write the AMA data, Isolate the SM, and Halt the Emulator
In preparation to powering down Netra t 1120 workstation, the SM should be placed
in isolation. AMA Data should also be written and the Emulator halted.
To do this, execute procedure 4.1, “Halt the Administrative Module (AM) Emulator“
from the DRM User’s Guide.
A5.7 Copy MHD Images and Configuration Files
1. Switch to the Sun console side of the MCC terminal. Log in as root. The root
password should have been obtained from the local 5ESS CTS organization.
2. Insert a blank tape Netra t 1120 Tape Drive.
3. This step will copy the MHDs (MHD 0 and MHD 2) with the office data and
5ESS Generic from the Netra t 1120 to tape.
Note: Please type carefully and check the input before hitting enter for the
“dd” commands. The character ‘n’ as the last character in the Output File tape
device name of the first “dd” command specifies a non-rewinding tape write. The
second “dd” command will cause the tape to rewind. These commands will each
