This document describes, how to solve the problem, that the ILOM doesn't show any information about the internal storage (hard disks) of a T3/T4/T5 servers.

Symptoms

Storage health status "Not Available", as seen in the ILOM Command Line Interface:

-> show /System/Storage/Disks/Disk_0

/System/Storage/Disks/Disk_0
    Targets:

    Properties:
        health = Not Available
        health_details = Comprehensive System monitoring is not available.

Cause

This problem is caused by:

- either by the lack of the Oracle Hardware Management Pack (OHMP) Software on the affected Host OS
- or by an error in the configuration of the already installed Oracle Hardware Management Pack Software,

which prohibits, that the OHMP Software passes the information about the internal Storage to the ILOM.

Solution

To resolve the problem:

1. Install the Oracle Hardware Management Pack (OHMP) Software by following the OHMP 2.2.x Installation Guide

2. After successful installation, the hwmgmtd Service should be running. To check, if this service is running, execute:

# svcs | grep hwm
online 15:02:55 svc:/application/management/hwmgmtd:default

3. After successful installation, the following configuration file of the hwmgmtd Service should exist in the installation directory of the OHMP software:

/<OHMP_Installation_Directory>/sun-ssm/hwmgmtd.conf

Usually, the default location will be:

/etc/opt/sun-ssm/hwmgmtd.conf

The content of this file will be similar to the following:

# Empty lines and lines beginning with '#' are ignored
# property format: "%s=%[^\n]\n"
# log for hwmgmtd agent
#   Solaris default is /var/log/sun-ssm/hwmgmtd .log
#   Linux default is /var/log/sun-ssm/hwmgmtd .log
#hwagentd.log=/var/log/sun-ssm/hwmgmtd .log
#hwagentd_log_levels
#hwagentd_log_levels=ERROR      - error messages
#hwagentd_log_levels=WARNING    - error messages and warnings
#hwagentd_log_levels=INFO       - error messages and warnings and informational
hwagentd_log_levels=ERROR
ipmitool_interface=bmc

4. Please check, if the mentioned configuration file of the hwmgmtd Service contains the line:

storage_poller_enabled=0

If the configuration file contains this line, please remove or change this line to "storage_poller_enabled=1", preferred method would be to just remove it, as that is the default behavior.

5. Restart the hwmgmtd Service

On a Solaris 10 system:
# svcadm restart hwmgmtd

On a Solaris 11 system:
# svcadm restart svc:/system/sp/management:default

6. The steps described above should immediately make the Storage/Disks Information available in the ILOM.

If you're connected to the ILOM Browser User Interface and if the Storage/Disks information still is not displayed,
it might be necessary to open the tab with the Storage overview again, or even to log out from the session and to log back in.

If this doesn't help, and if also the ILOM Command Line Interface still doesn't show the status of the Storage/Disks, please reset the SP: How to reset the SP on a T3-x and T4-x (Doc ID 1541150.1)

7. In the unlikely case that the problem persists, please collect an ILOM snapshot and explorer output, and open a Service Request at Oracle for further analysis.

8. After resolution of the problem:

- This problem has been documented in Bug 17257017 : ILOM SHOWS STORAGE STATUS "NOT AVAILABLE" ON SPARC T5-4

- The resolution is targeted for OHMP 2.3. See also the following mailfiner conversation: Click here to view it

- Frank Schwippe was able to reproduce the customer's problem on a lab system on a Netra T3-1, and the steps described above
has resolved the issue (by adding "storage_poller_enabled=1" to the hwmgmtd.conf file). See collab SR 3-7852602541

We've then tried to reproduce the problematic situation by removing the line "storage_poller_enabled=1", restarting the hwmgmtd
service and even by rebooting the OS and reseting the SP. But it wasn't possible anymore to create the problematic situation.
The status of the HDDs was always correctly visible in the SP (ILOM BUI and CLI).
