This article mainly shows you "how to use MegaRAID tools", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "how to use MegaRAID tools" this article.

DELL raid card management tool MegaRAID Storage Manager (emphasis on RAID common management commands)

1. Download address of MSM

Linux-4.6-CC 2.0

Www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/8.33-01_Linux_MSM.zip

Windows-4.6-CC 2.0

Www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/8.33-01_Windows_MSM.zip

The above version does not include the command line tool MegaCli. In order to support the CacheCade function, you need to use the above version (both versions are supported in the actual test, but not in the official lsi software description). Otherwise, please use the following link to download and include the command tool MegaCli-8.02.14-1.i386.rpm

Linux-4. 6-11M06

Www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/11.06.00-05_Linux_MSM.zip

II. Prerequisite for software installation

1. Check the server type. The test environment is DELL R610.

# dmidecode-s system-product-name

PowerEdge R610

2. Confirm whether to use LSI MegaRAID card

# dmidecode | grep "RAID"

Description: Integrated RAID Controller

Reference Designation: Integrated RAID

# lspci | grep RAID

03Symbios Logic LSI MegaSAS 00.0 RAID bus controller: LSI Logic / Symbios Logic LSI MegaSAS 9260 (rev 05)

# dmesg | grep "RAID"

Scsi0: LSI SAS based MegaRAID driver

3. Controller models are supported. See the package content file "8.33-01_Linux_MSM.txt".

The contents are as follows:

Supported Controllers

=

MegaRAID SAS 9265-8i

MegaRAID SAS 9285-8e

MegaRAID SAS 9240-4i

MegaRAID SAS 9240-8i

MegaRAID SAS 9260-4i

MegaRAID SAS 9260CV-4i

MegaRAID SAS 9260-8i

. The content is slightly...

MegaRAID SAS 8480E *

MegaRAID SATA 300-8ELP *

* These older controllers should work but have not been tested.

. The content is slightly...

Third, install MegaRAID Storage Manager version 8.33.0100

System test environment: RHEL 5.5_64bit

1. Software dependency relationship

Compat-libstdc++-33-3.2.3-61.x86_64.rpm

Libstdc++-4.1.2-48.el5.x86_64.rpm

Net-snmp-5.3.2.2-9.el5.x86_64.rpm

Net-snmp-utils-5.3.2.2-9.el5.x86_64.rpm

two。 Install MSM

# unzip 8.33-01_Linux_MSM.zip

# cd disk

# install.sh

3. Just choose according to the prompts, we choose the full installation

(1)-Complete

This option will install all program features.

4. Installed software packages include

(1) Lib_Utils (2) Lib_Utils2 (3) MegaRAID_Storage_Manager-8.33-01 (4) sas_snmp-3.17-1119

5. Install raid card command line management tool MegaCli

# rpm-ivh MegaCli-8.02.14-1.i386.rpm

Or replace the installation location to facilitate command line operation

# rpm-relocate / opt/=/usr/sbin/-I MegaCli-8.02.14-1.i386.rpm

Confirm the installation location of the MegaCli package

# rpm-ql MegaCli

/ opt/MegaRAID/MegaCli/MegaCli # 32bit installation location

/ opt/MegaRAID/MegaCli/MegaCli64 # 64bit installation location, the experimental environment for this

4. The common commands of MegaCli are:

Tip: first the interpretation of the command, then the specific content of the command.

1. Command help

MegaCli64-help |-h |?

two。 Set adapter properties

Here we take enabling the CopyBack function as an example to explain the syntax: the vale value of 0 is to enable the corresponding function, here it is disabled for Enable Copyback,1,-an is followed by an orchestration number, and generally an adapter is specified as-a0 or ALL. The specific parameters are subject to the help instructions, and the syntax of other commands is the same.

8.1 caching policy terms explain:

8.1.1 Write Policy (write policy)

Sets the cache method to write back or through write.

In the WT (Write through) (by write) cache, when the disk subsystem has received all the data in a transaction, the controller sends a data transmission completion signal to the host.

In the WB (Write back) (writeback) cache, when the controller cache has received all the data in a transaction, the controller sends a data transmission completion signal to the host.

Write-through caches have data security advantages over Write-back caches, but Write-back caches have performance advantages over Write-through caches.

8.1.2 Read-ahead (pre-read) enables SCSI read-ahead for logical drives.

You can set this parameter to No-Read-Ahead (not pre-read), Read-ahead (pre-read), or Adaptive (adaptive). Default setting is Adaptive (adaptive).

NORA (No read ahead) (not pre-read) specifies that the controller does not use pre-read in the current logical drive.

RA (Read ahead) (pre-read) specifies that the controller uses pre-read in the current logical drive.

ADRA (Adaptive read ahead) (adaptive) specifies that if the last two disk accesses occur in contiguous sectors, the controller starts using Read-ahead (read-ahead). If all read requests are random, the algorithm replies to No-Read-Ahead (not pre-read), but still determines whether it is possible for all read requests to operate sequentially.

8.1.3 Cache Policy (caching policy)

Suitable for reading on a specific logical drive. It does not affect the Read ahead (read-ahead) cache.

Cached (cache Istroke O) specifies that all read data is cached in cache memory.

Direct specifies that read data is not cached in cache memory. This is the default setting. It does not replace the cache policy setting. The data is transferred to both the cache and the host. If the same data block is read again, it is read from the cache memory.

There are a lot of command line please see help, so not only to sigh the power of the command line, the graphical interface can do the same command line can do, the command line can not necessarily do the graphics!

5. Let's introduce the MSM graphical interface (the method is relatively easy to use, so I won't repeat it):

Experimental environment:

Server:rhel5.5_64bit, install MSM full mode

Client: win7, install client mode

5.1 launch interface

5.2 add a remote managed sever

5.3Login to remote server, login account password is remote server system user and password

MSM graphical interface, the lower part of the interface is log information, of course, the command line also has log

5.5 shut down and start MSM:

/ init.d/vivaldiframeworkd stop

/ etc/init.d/mrmonitor stop

/ init.d/vivaldiframeworkd start

/ etc/init.d/mrmonitor start

5.6 Uninstall MSM:

/ usr/local/MegaRAID Storage Manager/uninstaller.sh

LSI MegaRAID Storage Manager Array Management Software (MSM) remote management tools the Server side uses ports 3071 and 5571. If you cannot connect, you need to disable the firewall or open ports 3071 and 5571.
