SR 2.5 and SR 3.5 Upgrade Procedures

for the Enterprise 450 and Sun Fire V880 DNCS

Install the DNCS Software on an Enterprise 450 or Sun Fire V880 DNCS

Introduction

In this section, you will install the SR 2.5 or SR 3.5 software on to an Enterprise 450

or Sun Fire V880 DNCS.
Note: If you have followed the instructions in this upgrade guide in order, the

DBDS Maintenance CD should still be in the CD drive of the DNCS, and you should

still be logged on to an xterm window on the DNCS as root user.

CAUTION:

If you have entries in the /etc/vfstab file to automatically mount NFS file

systems, you need to comment out those specific entries prior to running this

procedure. The pkgadd command is likely to fail in a Live Upgrade

environment if there are NFS mounts present in the /etc/vfstab file; commenting

these entries out resolves the issue. You need to put these entries back manually

after the upgrade is complete, or after you have rolled back the system.
