Software Upgrade Procedures
Step 4 On a system with redundant NPs, verify that you are connected to the primary NP (the
active NP):
• At the bash prompt, enter the cli command to start the CLI.
bash# cli
• At the CLI prompt, enter the show chassis command and examine the entries for “Slot
of Primary NP” and “Slot of This NP.”
• Determine whether the entries for Slot of Primary NP and Slot of This NP identify the
same NP number or not.
• Use the exit or quit command to exit from the CLI.
Step 5 If you are connected to the backup NP, disconnect from it and connect to the primary NP
(the active NP) as follows:
• Enter ‘. (backquote plus dot, that is, left single quote plus period) to return to the TCS
HUB.
• Connect to the slot of the primary NP by typing the following command:
TCS HUB<<A>> connect primary
• If necessary, log in to the NP as root.
Copy Release 2.0.9 Software from Floppies to Hard Disk
Step 6 Determine which floppy disk drive is appropriate to use for the upgrade. NP slot 1 is
connected to the bottom disk drive, and NP slot 2 is connected to the top disk drive.
The boot disk is not used in this upgrade procedure. You will run the swinstall utility once
for each diskette set. If you are currently running any version from Version 2.0.3 through
2.0.8a3, install the diskette sets in this order: system, application, diagnostics, firmware.
Step 7 Enter the swinstall command at the bash prompt:
bash# swinstall
If the two entries identify the same NP number, then you are connected to the primary NP (the
active NP). Since you connected to slot 1 in Step 2 above, the following is true:
primary= 1
backup= 2
Make a note of this. You will use the value 1 where you see the parameter name “primary” in
later procedures.
If the two entries do not identify the same NP number, then you are connected to the backup NP.
Since you connected to slot 1 in Step 2 above, the following is true:
primary = 2
backup = 1
Make a note of this. You will use the value 2 where you see the parameter name “primary” in
Step 5, below, and in other procedures.
If the swinstall program reports that there is insufficient disk space for the installation, carry out
Special Procedure A, Freeing Up Disk Space, before continuing.
