Dell OpenManage

This page will focus on Dell OpenManage on Linux only.

Installation

Install Dell's OpenManage programs from their repository available at http://linux.dell.com/repo/hardware/. You can either manually install the packages or run their bootstraper script to install their repository.

## From http://linux.dell.com/repo/hardware/DSU_16.12.00/
# wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash 

## Install everything
# yum install srvadmin-\*

## Or -- just the CLI tools:
# yum install srvadmin-\*-cli

Once installed, the binaries can be found in /opt/dell/srvadmin/bin. You may want to append this path to your PATH variable.

# PATH=$PATH:/opt/dell/srvadmin/bin

You may also need to manually start some services such as the data engine service in order to query hardware information about storage systems by running /opt/dell/srvadmin/sbin/dsm_sa_datamgrd.

Usage

Open Manage Report Utility (omreport)

Run omreport -? for a list of available options on your system.

Storage System

To monitor your server's RAID array, run:

# omreport storage pdisk controller=0

Open Mange Configuration Utility (omconfig)

Creating a new vdisk

Suppose you need to create a new vdisk after inserting a new disk into an empty slot on your server. Use omconfig to set up the disk.

Find the disk using

# omreport storage pdisk controller=0 | grep -E '^(ID|Status|Capacity|Sector Size)'

If you're not sure what controller ID to use, you can find it by running omreport storage controller.

# omreport storage controller

To create the vdisk using the disk above:

# omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:1:6 writepolicy=fwb name=disk06
Command successful!

The different write policies are talked about in a section below.

Deleting a vdisk

To delete a vdisk, determine the vdisk ID using omreport

omreport storage vdisk controller=1 | grep -E '^(ID|Device Name)'

and then run:

omconfig storage vdisk action=deletevdisk controller=1 vdisk=123

Wiping Foreign Configs

To wipe foreign configs on all drives attached to a controller:

# omconfig storage controller action=clearforeignconfig controller=1
Command successful!

Write Policy

You can change the disk's write policy using omconfig.

# omconfig storage vdisk action=changepolicy writepolicy=fwb controller=0 vdisk=0

Available options are:

• wb - Write Back
• wt - Write Through
• wc - ?
• nwc - ?
• fwb - Force Write Back (even with no battery)
