Megacli Download Dos

Have anyone been able to install megacli on esxi 7 ? I have googled a lot but haven't found anything that explains this for esxi 7. I have tried several methods for esxi 6.7 and esxi 5 but it doesn't work for esxi 7.

Everyone who has worked with specific vendors servers for awhile has likely encountered megacli. This is the comman line tool to manage your RAID controller and disks. Since often I'll only end up doing this every six months or so, I usually forget the syntax and decided to write it down here.

This morning I came to reconfigure a raid array on an old Dell Perc5i with the LSI MegaRAID CLI tool megacli, and whilst displaying information and removing an old LD appeared to work fine, I was greeted with the following when trying to add a new LD:

Select an unconfigured good drive from the "Drives" menu and click on Properties. Here, you can configure the drive either as a dedicated hot spare for an array or as a global hot spare for all arrays. You can also do this using the megacli tool

If the drive is good, it can now replace the missing drive. To do this, you need to specify the array and the position which are going to be replaced. You can get these numbers, for example, from megacli -CfgDsply -a0.If a drive is missing in an array, the entry Physical Disk: will show up, but no further information will be displayed. In the example, the fourth drive of the first array Array0 is now exchanged with the drive in Enclosure 245 Slot 3 ("PhysDrv[245:3]"):

There is currently no known opensource tool for theses cards.

Some old MegaRAID SAS can be used with megactl, but none of current cards works.

However LSI provide megacli, a proprietary management command line utility which is rather hard to use.

megactl includes a SAS compliant binary named megasasctl. It seems to work on old card but fails with the new one.

If megasasctl doesn't work for you, you will have to use the proprietary cli utility from LSI: megaclisas.

megacli is a proprietary tool by LSI which can perform both reporting and management for MegaRAID SAS cards.

However it's really hard to use because it's use tones of command line parameters and there's no documentation.

megaclisas-status is a wrapper script around megacli that report summarized RAID status with periodic checks feature.

It is available in the packages repository too.

The packages comes with a python wrapper around megacli and an initscript that periodic run this wrapper to check status.

It keeps a file with latest status and thus is able to detect RAID status changes and/or brokeness.

It will log a ligne to syslog when something failed and will send you a mail.

Until arrays are healthy again a reminder will be sent each 2 hours.

Given that a .service file for this megacli app was created, you should be able to use

systemctl enable megacli to start the automatically start the app at every boot.

systemctl start megacliwill start the app as a service right now.

MegaCli introduced by LSI is a command line administration of LSI MegaRaid controllers .

With megacli we can create physical raids, gather info about raids and monitor raids.

MegaCLI provided by LSI is the most cryptic command line utility in existence.

Dell PowerEdge servers uses the LSI MegaRAID controllers

In order to communicate with the LSI card you will need the MegaCLI orMegaCLI64 (64bit) program. The install should be quite easy, but LSI make usjump through a few hoops. This is what we found: Go to the LSI Downloads page: LSI Downloads Search by keyword "megacli Click on "Management Software and Tools" Download the MegaCLI zip file. You will see the same file is for DOS, Windows, Linux and FreeBSD. Unzip the file In the Linux directory there is an RPM. If you are using Redhat you can install it. For Ubuntu got the next step. For Ubuntu run "rpm2cpio MegaCli-*.rpm | cpio -idmv" to expand the directory structure. You may need to "apt-get install rpm2cpio" . For FreeBSD unzip the file in the FreeBSD directory.On our Ubuntu Linux 64bit and FreeBSD 64bit servers we simply copiedMegaCli64 (64bit) to /usr/local/sbin/ . You can put the binary anywhere youwant, but we choose /usr/local/sbin/ because it is in root's path. Make sure tosecure the binary. Make the owner root and chmod the binary to 700 (chown root/usr/local/sbin/MegaCli64; chmod 700 /usr/local/sbin/MegaCli64). The install isnow done. We would like to see LSI make a Ubuntu PPA or FreeBSD ports entrysometime in the future, but this setup was not too bad.

Select an unused (unconfigured good) drive from the Drives menu and click on Properties. Here the drive can be configured either as a dedicated hot spare for an array or as a global hot spare for all arrays. This is also possible via the megacli tool

If the drive is good, it can now replace the missing drive. To do this the array and the position which are to be replaced need to be specified. These numbers may be obtained for example from megacli -CfgDsply -a0. If a drive is missing in an array, the entry Physical Disk: will show up, but no further information will be displayed. In the example, the fourth drive of the first array (Array0) is now exchanged with the drive in Enclosure 245 Slot 3 (PhysDrv[245:3]): 17dc91bb1f
