Eu tenho HP DL 380G4 morto com RAID 1 + 0 com 1 volume lógico de 4x72GB no Smart Array 6i 128Mb BBWC. Foi desligado corretamente. Parece que foi morte normal para Proliant com ILO levou 2,3,8 iluminação. Eu quero mover a matriz para outro servidor idêntico com o mesmo nível de firmware de ataque.
Qual é a melhor estratégia ?:
Eu tenho RAID 1 + 0 em
baía 0
baía 1
baía 2
baía 3
Pelo que entendi, bay0 + bay1 estão no RAID 1, bay2 + bay3 estão no RAID 1 e ambos os pares do RAID 1 estão no RAID 0.
Então eu deveria:
Limpe a configuração RAID no novo servidor, insira o compartimento 0, o compartimento 2 e ligue-o
ou
Crie RAID 1 + 0 com 1 volume lógico de HDDs limpos e, em seguida, desligue, remova os HDDs e insira 2 HDDs (compartimento 0, compartimento 2) do antigo RAID 1 + 0. depois ligue. (cada disco rígido tem suas informações de posição de ataque armazenadas, mas pode funcionar na mesma configuração)
De acordo com a documentação do Smart Array 6i, é possível migrar. no entanto, um ponto de requisito não é claro para mim
Before you move drives, the following conditions must be met:
• The array is in its original configuration. "
O que é a configuração original e não original para o RAID 1 + 0?
Outro ponto
"If you want to move an array to another controller, you must also
consider the following additional limitations: • All drives in the
array must be moved at the same time."
Eu quero mover um disco rígido de cada par RAID 1. ter espelhos intocados apenas no caso.
Eles pretendem mover todos os 4 simultaneamente?
Smart Array 6i User Guide: Moving Drives and Arrays
You can move drives to other ID positionson the same array controller.
You can also move a complete arrayfrom one controller to another,
even if the controllers are on different servers.
Before you move drives, the following conditions must be met:
• If moving thedrives to a different server, the new server must have
enough empty bays to accommodate all the drives simultaneously.
• The move will not result in more than 14 physical drives per
controller channel.
• No controller will be configured with more
than 32 logical volumes.
• The array has no failed or missing
drives.
• The array is in its original configuration.
• The controller is not reading from or writing to any of the spare drives
in the array.
• The controller is not running capacity expansion,
capacity extension, or RAID or stripe size migration.
• The controller is using the latestfirmware version (recommended).
If you want to move an array to another controller, you must also
consider the following additional limitations:
• All drives in the array must be moved at the same time.
• In most cases, a moved array
(and the logical drives that it contains) can still undergo
arraycapacity expansion, logical drive capacity extension, or
migration of RAID level orstripe size.
When all the conditions have been met:
- Back up all data before removing any drives or changing configuration. This step is requiredif you are moving data-containing
drives from a controller that does not have a battery-backed cache.
- Power down the system.
- If you are moving an array from a controller that contains a RAID ADG logical volume to a controller that does not support RAID ADG:
- Move the drives.
- Power up the system. If a 1724 POST message is displayed, drive positions were changed successfully and the configuration was
updated. If a 1785 (NotConfigured)POST message is displayed: a.
Power down the system immediately to prevent data loss. b. Return
the drives to their original locations. c. Restore the data from
backup, if necessary.
- Check the new drive configuration byrunning ORCA or ACU ("Configuring an Array" on page 9).
