Some commands:

<code>
MegaCli -AdpAllinfo -aALL
MegaCli -AdpEventLog -GetEvents -f eventlog.txt -aAll

</code>

How do I replace a failed drive:

<code>
# Show Drive Information
./storcli /c0/eall/sall show

# Set the failed drive
./storcli /c0/e245/s4 set offline

# Set the failed drive as missing
./storcli /c0/e245/s4 set missing

# Spindown the failed drive
./storcli /c0/eall/s4 spindown

# Locale drive
./storcli /cx[/ex]/sx start locate
./storcli /cx[/ex]/sx stop locate

# Show rebuild
./storcli /c0/eall/sall show rebuild

</code>

== spare drive ==

<code>
# Add drive hotsparedrive global
./storcli /cx[/ex]/sx add hotsparedrive

# sample
./storcli /c0/e32/s8 set good force
./storcli /c0/e32/s8 add hotsparedrive

</code>

== alarm control ==

<code>
# MegaCli64 -AdpSetProp <AlarmEnbl | AlarmDsbl | AlarmSilence> -aN
# storcli /cx set alarm=<on | off | silence>

</code>

== buscar serial number ==
<code>

# ./storcli /c0/eall/sall show all | egrep 'Device attributes|SN = '

</code>

== converter VD de RAID0 para RAID1 ==
<code>

# ./megacli -ldrecon -start -r1 -add -physdrv[Enc:Slot] -l???VD??? -aAdaptadorID
# ./megacli -ldrecon -start -r1 -add -physdrv[252:1] -l0 -a0

</code>

== Como remover um disco de um pool e colocar para ser RAID1 de um RAID0 ==

<code>
# ./megaclisas-status
# ./storcli /c0/eall/sall show
# ./storcli /c0/e252/s1 set offline
# ./storcli /c0/e252/s1 set missing
# ./storcli /c0/eall/sall show
# ./megacli -ldrecon -start -r1 -add -physdrv[252:1] -l0 -a0
# ./megaclisas-status

</code>

== Cópia da tabela de partição ==

<code>
sfdisk -d /dev/sdc | sfdisk /dev/sdb

</code>

== mdadm (raid via software) ==
<code>

# mdadm --detail /dev/md127
# mdadm --stop --scan
# mdadm --assemble --scan
# opção com force:
mdadm --stop /dev/md1
mdadm --assemble --scan --force

</code>

== mdadm (raid via software) - replace ==

<code>
# mdadm --query --detail /dev/md2
# cat /proc/mdstat
## Remove the failing disk from the RAID array
# mdadm --manage /dev/md2 --remove /dev/sdb4
## para ver o serial do disco: lsblk -o NAME,SERIAL,SIZE
# cat /proc/mdstat
## Shut down the machine and replace the disk
## Create partition raid ;)
## para copiar a estrutura de tabela de partição: sudo sfdisk -d /dev/sda | sudo sfdisk /dev/sdb 
## Add the new disk to the RAID array
# mdadm --manage /dev/md2 --add /dev/sdb4
# cat /proc/mdstat
# mdadm --query --detail /dev/md2
## caso o disco seja do sistema, cuidado com o grub, pois pode ser que estaja com o grub em apenas em um dos discos para reinstalar basta rodar o grub2-install em ambos os discos : grub2-install /dev/sda ; grub2-install /dev/sdb
