I have already successfully installed MegaCli to OpenFiler but I'm stuck in figuring out the correct command line for creating a raid 10 array. I have googled high and low but there doesn't seem to be any example doing raid10 with megaraid only the syntax. You didn't understand the man page. ES02 - its like variable which should have int values.
All you need:. This is you E and S numbers, i. Assuming there is only one controller in these examples, so that -aALL can be used instead of specifying a particular controller. Note the "Enclosure Device ID" and "slot number" for the drives from this list as these are the numbers you replace "E" and "S" with, respectively, in the later raid-set creation commands.
If you have an existing RAID array which you are going to re-use disks from then you need to remove the existing logical drive which those disks are part of. The logical drive number should be obtained from the previous command. Obviously this will destroy the data on this existing RAID array if you run it :. Now you have a bunch of disks which should be in the "Unconfigured good " state and hence are available for use in a new logical drive.
In my case the disks are disks 2 to 7 on enclosure These numbers are obtained from the PDList output you got earlier. MegaCli cfgspanadd r10 array0 "[,]" array1 "[,]" wb cached nocachedbadbbu a0 should work without problems. Sign up to join this community.

Seems that I should not use E and S letters.MegaCli not providing all the information we need like mapping to linux devices and raid level readableso we are going to use some extra tools. Adapter - The physical controller which we are going to use, represented by id usually 0. Enclosure - The physical chassis the physical drives attached to, represented by id, such asetc.
Physical Drives - Physical Hard Disks attached to controller, represented by id, 0,1,2,3 etc.
MegaCLI: useful commands
Virtual Drive contains physical drives 0,1 and 2 and includes the settings of the raid device such as raid level, strip size etc. We can see configurations in megacli like Virtual Drive with RAID 0 over one physical drive, we have this settings because physical drives attached to raid controller, and for representing the device to the system we must set it in megacli.
Actually this slot number will be used to represent this physical ID drive in other commands.Что такое RAID и как оно работает?
As we look for simple output that shows the virtual drives structure, its hard to get that with megacli. We can see here Primary raid level 1 and secondary 0. It means actually raid 0 over raid 1 that is RAID Eventually we want to get the information about the mapping between linux devices and virtual drives raid devices. Cache Policy's are how the raid card uses on board RAM to collect data before writing out to disk or to read data before the system asks for it.
Write cache is used when we have a lot of data to write and it is faster to write data sequentially to disk instead of writing small chunks.
Read cache is used when the system has asked for some data and the raid card keeps the data in cache in case the system asks for the same data again. It is always faster to read and write to cache then to access spinning disks. Understand that you should only use caching if you have good UPS power to the system. If the system looses power and does not flush the cache it is possible to loose data. No one wants that. Lets look at each cache policy LSI raid card use. Jump to: navigationsearch.

This command displays the firmware log which includes environmental data, controller properties, memory information, events, and information about the Battery Backup Unit BBU such as physical properties, monitored information, capacity, and design information.
The output also provides event messages specific to the BBU. Displays information about all physical disk drives and other devices connected to the selected adapter s ; includes drive type, size, serial number, and firmware version. For SAS expanders: includes number of drives connected to expander.
If the customer cannot install the MegaCLI utility or it is not available for some other reason, you can get to the Preboot CLI and run the same commands as shown above. Contents Introduction.MegaCli commands have presented a number of questions among our users for Cisco's Physical Security.
Here is an attempt to explain thier meaning and uses. For commands that operate on one or more pysical drives, the -PhysDrv [E:S] parameter is used, where E is the enclosure device ID in which the drive resides and S the slot number starting with zero. The parameter -Lx is used for specifying the virtual drive where x is a number starting with zero or the string all. For VSM systems it's normally 0.
On every instance of a hard drive problem with an MSP server, we need to run the following commands to have any information about the problem:.
Collect the MegaSAS. You may use a program such as WinSCP freeware to pull the files off of the server. Hi, I have a big problem with one Raid 5 array. Someone known if we can reintroduce a drive mark failed in the array with MegaCli? I explain my problem:. My enclosure has 12 drives. I put 11 disks in Raid 5 and 1 Hot swap Disk.
Monday I lost 1 disk. The HSP disk start to rebuild but after some minute, I lost a second disk. But after some manipulation, I was able to repair one disk I lost disk 5 and after I lost 3, I repair disk 3 by change the electonic board.
So, is-it possible to say at the Array that Disk3 are OK and is part of the array and after that I can transfert my data on other disk I don't have Backup of that Raid 5 Array? Buy or Renew. Find A Community. Cisco Community.

Virtual drive parameter -Lx The parameter -Lx is used for specifying the virtual drive where x is a number starting with zero or the string all. Tags: megaraid. Cisco Employee. Usage example: I had a couple systems down at a customer site after a power failure.
When we got to the consoles the 2 systems that were down we saw they were waiting for someone to acknowledge the battery backup was missing on the raid controllers. After we acknowledged those and allowed them to reboot all the way they came back online.You can see your options by looking at the raid adapter settings top of this page. Include the square brackets.
When you replace controllers, you can duplicate the previous config. Be sure that your disk array is healthy first. At this point, an analogy may make things more interesting, even if most readers already fully understand what I am saying.
Assuming you have to carry eight squares of cargo, which would you prefer: two four-unit battleships or four two-unit destroyers? When the bombs start falling, you would much prefer to have your cargo in four different locations.
Forcing Murphy to precisely take out both disks in the same mirror for example both yellows from the left picturerather than one disk from each stripe is a better strategy.
It is the fundamental building block of the array. I suspect that he manually created the striped disks then mirrored them and that megacli did not keep track of all the steps. Tiago Cruz said:.

We have all been looking at that site, but what we are looking for is documentation from the megacli command and what it should show for primary and secondary values for RAID1 versus RAID June 11, at pm.
Magnus said:. August 15, at pm. How about expanding a raid array, that i have not seen anyone discuss, not even the LSI documents. Is it possible?Please note: This emergency cheat sheet is not exhaustive, but it should be sufficient in most cases.
While there are a lot of different parameters for MegaCli, some of them are always identical. These are described here in short. Physical drive parameter -PhysDrv [E:S] For commands that operate on one or more pysical drives, the -PhysDrv [E:S] parameter is used, where E is the enclosure device ID in which the drive resides and S the slot number starting with zero. Virtual drive parameter -Lx The parameter -Lx is used for specifying the virtual drive where x is a number starting with zero or the string all.
Share on Facebook. The link with full commands is dead, can you repost a new link? Great references!!! This is part of our standarnd build now and the commands are great to utilize automation. No help from LSI. Thanks for spending the time to put this together!!! Hey guys what is the command for make the leds on the physical drives to light again,cant tell which drive is failing on visual check. I can not even count the number of times I have come back to this page as reference because the official documentation is … well, LSI.
