Symptom

A user runs the following command to preconfigure the U2000:

# cd /opt/OSSICMR/bin

# ./install.sh -r

The operation fails in the "Encapsulating disk group" step.

Cause Analysis

The /var/ICMR/ICMR_Timestamp.log file records some errors, as follows:

The error information reveals that the installer failed to read size and other information about hard disk c2t3d0 and found no other hard disk suitable for the appdg group. As a result, the hard disk group failed to be encapsulated.

The log file also records the following output for the format command:

20150322130332  DEBUG   core::runcommand:RunCommandLocal        2223    The output is: "Searching for disks...done

AVAILABLE DISK SELECTIONS:

Specify disk (enter its number): "

The command output reveals that hard disk c2t3d0 was in the unknown state and therefore unrecognizable to the installer.

Solution

                               Step 1     Contact the disk manufacturer to replace the faulty hard disk.

                               Step 2     Install the U2000 again.

----End

Suggestion and Summary

Check hardware before installing the U2000.
