Upgrading the MSA
NOTE:
Before performing these migration steps, complete all prerequisites. (See
Preparing for the
migration
.)
Step
Description
Check
1
Notify all system units in the MSA SAN fabric that the MSA is going offline.
2
Back up all operating system and data volumes.
3
Verify successful backup of the operating system and data volumes.
4
Isolate the MSA from the network. Be sure to:
•
Disable all applications (including daemons, cron jobs, and cluster services).
•
Unmount the MSA volumes
on all system
s with access to the MSA.
5
For environments currently using Secure Path:
NOTE:
Before proceeding, understand the following:
•
HP Secure Path software can no longer be used to manage the MSA.
•
QLogic HBA failover driver is the only recognized method for managing
redundancy on active/active MSA in Linux environments.
•
This step runs a utility that prepares MSA LUNs currently managed by Secure Path
for the Qlogic failover driver. This utility enables a smooth transition of the MSA
from Secure Path and ensures that applications using the MSA do not require any
configuration changes.
•
This utility creates the
/opt/hp/hp-devlabel
directory and copies scripts
necessary for migrations. It also copies operating-system-specific binaries and
scripts to the
/usr/bin/hp
and
/sbin
system directories.
•
In addition to removing Secure Path and migrating the LUNs, this utility adds
persistency to the LUNs. This information is maintained in
/etc/sysconfig/hpdevlabel
. HP recommends that you do not edit this file.
a.
Log on to the Linux system as a super user (
root
).
b.
Navigate to the temporary directory containing
LMPutils.tar.gz
.
(See
Preparing for the migration
.)
c.
Enter the following commands to extract and install the hpdevlabel utility:
# tar -zxvf LMPutils.tar.gz
# cd ./LMPutils
# ./install.sh
d.
Wait for the Linux Lun Migration and Lun Persistence installer menu to display.
e.
At the menu prompt, enter:
1
Lun Migration with Lun persistency
.
f.
View the display for status and completion messages, and then proceed to the
step 6 in these instructions. The latest supported Qlogic failover driver is
installed and activated in later steps of these migration procedures.
