136.159.5.78: /* Wiping Foreign Configs */

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.

{{highlight|lang=terminal|code=
## 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 {{code|/opt/dell/srvadmin/bin}}. You may want to append this path to your {{code|PATH}} variable.
{{highlight|lang=terminal|code=
# 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 {{code|/opt/dell/srvadmin/sbin/dsm_sa_datamgrd}}.

== Usage ==

=== Open Manage Report Utility (omreport) ===

Run {{code|omreport -?}} for a list of available options on your system.

==== Storage System ====
To monitor your server's RAID array, run:

{{highlight|lang=terminal|code=
# omreport storage pdisk controller=0|egrep "^ID |Status|State|Failure"
ID : 0:0:0
Status : Ok
Power Status : Spun Up
State : Online
Failure Predicted : No
ID : 0:0:1
Status : Ok
Power Status : Spun Up
State : Online
Failure Predicted : No

# omreport storage vdisk|egrep "^Name|State|Write|Read"
Name : root
State : Ready
Read Policy : Adaptive Read Ahead
Write Policy : Write Back
Name : data
State : Ready
Read Policy : Adaptive Read Ahead
Write Policy : Write Back
Name : root
State : Ready
Read Policy : Adaptive Read Ahead
Write Policy : Write Back
Name : data
State : Ready
Read Policy : Adaptive Read Ahead
Write Policy : Write Back

# omreport storage controller|egrep "^ID|^State|^Status|^Firmware"

State : Ready
Firmware Version : 12.3.0-0032
Controller Battery
[root@sdw1 ~]# omreport storage battery

}}

=== 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 {{code|omconfig}} to set up the disk.

Find the disk using

{{highlight|lang=terminal|code=
# omreport storage pdisk controller=0 {{!}} grep -E '^(ID{{!}}Status{{!}}Capacity{{!}}Sector Size{{!}}Bus{{!}}Power{{!}}Media)'
}}

If you're not sure what controller ID to use, you can find it by running {{code|1=omreport storage controller}}.

{{highlight|lang=terminal|code=
# omreport storage controller

# omreport storage pdisk controller=0 {{!}} grep -E '^(ID{{!}}Status{{!}}Capacity{{!}}Sector Size{{!}}Bus{{!}}Power{{!}}Media)'
ID : 0:1:6
Status : Ready
Power Status : Not Applicable
Bus Protocol : SATA
Media : HDD
Capacity : 1,396.75 GB (1499748892672 bytes)
Sector Size : 512B
}}

To create the vdisk using the disk above:
{{highlight|lang=terminal|code=
# 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 {{code|omreport}}

{{highlight|lang=terminal|code=
# omreport storage vdisk controller=0 {{!}} grep -E '^(ID{{!}}Name)'
ID : 0
Name : one
ID : 1
Name : two
ID : 2
Name : three
ID : 3
Name : four
ID : 4
Name : five
ID : 5
Name : six
}}

To delete six:
{{highlight|lang=terminal|code=
# omconfig storage vdisk action=deletevdisk controller=0 vdisk=six
}}

==== Wiping Foreign Configs ====
To wipe foreign configs on all drives attached to a controller:

{{highlight|lang=terminal|code=
# omreport storage pdisk controller=0
ID : 1:0:5
Status : Non-Critical
Name : Physical Disk 1:0:5
State : Foreign
...

# omconfig storage controller action=clearforeignconfig controller=0
Command successful!
}}

If this still doesn't work, try wiping the drive manually by plugging it to a toaster or computer and then running:

{{highlight|lang=terminal|code=
# dd bs=512 if=/dev/zero of=/dev/sdb count=2048
# dd bs=512 if=/dev/zero of=/dev/sdb count=2048 seek=$((`blockdev --getsz /dev/sdb` - 2048))
}}

If this *still* doesn't work, you might need to reboot.

==== Write Policy ====
You can change the disk's write policy using {{code|omconfig}}.

{{highlight|lang=terminal|code=
# omconfig storage vdisk action=changepolicy writepolicy=fwb controller=0 vdisk=0
}}

Available options are:
* {{code|wb}} - Write Back
* {{code|wt}} - Write Through
* {{code|wc}} - ?
* {{code|nwc}} - ?
* {{code|fwb}} - Force Write Back (even with no battery)
