MegaCli64 -LDRecon -Start -r5 -Add -PhysDrv -L0 -a0Ĭreate a new RAID 5 virtual disk from a set of new hard drivesįirst we need to now the enclosure and slot number of the hard drives we want to use for the new RAID disk. # /usr/local/sbin/MegaCli64 -LDRecon -Start -r5 -L0 -a0Įxtending an existing RAID array with a new disk. The second command is used to make Linux detect the new size of the RAID disk. In this example, I migrate the virtual disk 0 from RAID level 6 to RAID 5, so that the disk space of one additional disk becomes available. You could use the above commands to run patrol read in off-peak times. To stop a patrol read scan: # MegaCli64 -AdpPR -Stop -aALL
#Megacli check disk health manual#
To start a manual patrol read scan: # MegaCli64 -AdpPR -Start -aALL To disable automatic patrol read: # MegaCli64 -AdpPR -Dsbl -aALL To reduce patrol read resource usage to 2% in order to minimize the performance impact: # MegaCli64 -AdpSetProp PatrolReadRate 2 -aALL To find out the current patrol read rate, execute # MegaCli64 -AdpGetProp PatrolReadRate -aALL To see information about the patrol read state and the delay between patrol read runs: # MegaCli64 -AdpPR -Info -aALL By default it is done automatically (with a delay of 168 hours between different patrol reads) and will take up to 30% of IO resources. Patrol read is a feature which tries to discover disk error before it is too late and data is lost. View information about physical drives # MegaCli64 -PDList -aALL Useful for checking RAID level, stripe size, cache policy and RAID state: # MegaCli64 -LDInfo -Lall -aALL View information about the battery backup-up unit state # MegaCli64 -AdpBbuCmd -aAll I installed mc and rpm on Debian with apt-get, and then extracted the MegaCli64 binary (for x86_64) to /usr/local/sbin, and the libsysfs.so.2.0.2 from the Lib_utils RPM to /opt/lsi/3rdpartylibs/x86_64/ (that’s the location where MegaCli64 looks for this library).įor checking the firmware version, battery back-up unit presence, installed cache memory and the capabilities of the adapter: # MegaCli64 -AdpAllInfo -aAll
#Megacli check disk health archive#
The downloaded archive contains an RPM file. You can download it from their support pages. LSI created a command line utility called MegaCLI for Linux to manage this adapter. Recently I installed a server with a Supermicro SMC2108 RAID adapter, which is actually a LSI MegaRAID SAS 9260. Then save the file and run the below command to trust or sign the above site. Here i am installing on debian (promox in debian based) and jessie version (proxmox 4.4.1) Edit /etc/apt/sources.list add the entry deb jessie main
