However it’s really hard to use because it’s use tones of command line parameters and there’s no documentation. Until arrays are healthy again a reminder will be sent each 2 hours. BIOS upgrade from a Linux system. The first one with a RAID1 array working fine. With this option, readahead will only be enabled if the controller receive several access to sequencial sectors. Proprietary tools creates the device node at startup. It’s quite new and thus, may be missing in some not-up-to-date distributions.

I noticed that strange behavior on an IBM controller. Assuming your new unassigned drive is identified as! Even Ubuntu is listed in the wikipage, LSI card upgrade is not supported. Hosting sponsored by http: However, please that most of old distributions won’t have this driver.
Then you can expect such monitoring facilities centreon on-top centreon-engine in this picture:.
Write cache should be enabled ONLY if you have a battery pack on your controller. I made some wrappers around binaries from megactl package to create the node if it doesn’t exist yet.
It will log a ligne to syslog when something failed and will send you a mail. It means it has detected some RAID informations on it, and thus, considers it as a disk being part of an array that may be imported into current controller configuration.
With this option, readahead will only be enabled if the controller receive several access to sequencial sectors. The controller will now recognise the disk as being a “foreign” one.
Please note you need a recent version of smartmontools. The disk drive identified as! Powered by Trac 1. The read policies indicate whether or not the controller should read sequential sectors of the logical drive when seeking data. A complete documentation is attached as PDF here: You can write your own script around megasasctl to check your adapter status health periodically.
Proprietary tools creates the device node at startup.
LSI MegaRAID SAS
The first one is already setup but we have just plugged a disk bays on the second card. The first redyat with a RAID1 array working fine.
The first thing you’ll have to do is to list IDs of all your physical disks:. The packages comes with a python wrapper around megasasctl and an initscript that periodic run this wrapper to check status.
LSIMegaRAIDSAS – HWraid
All theses card can be used with stock Linux kernel which includes a working driver. It’s quite new and thus, may be missing in some not-up-to-date distributions. It is available in the packages repository too. However, I already did this for you.
BIOS upgrade from a Linux system. However it’s really hard to use because it’s use tones of command line parameters and there’s no documentation. Megadaid and pluging back a disk from an array doesn’t make the controller rebuild the array with that disk. Linux kernel drivers 3. Here is what to do:. We’re going to enable an enhanced version of readahead: It seems ADRA is deprecated, current megacli binary doesn’t offer this option anymore. These settings do not affect the read-ahead policy.
