NetApp存储如何将系统盘从RAID_DP改为RAID_4

NetApp存储初始化系统必须要有系统盘要么就是使用6块单独的硬盘来做系统要么就是做ADP分区。如果是单块磁盘容量 较大且数量少的情况那使用ADP分区来做系统是比较合适的。但是如果是盘的数量比较多而且单个盘的容量较小的情况 下可能有没必要进行ADP分区来做系统了可以使用单独盘来做系统但是就会占用6个盘每个控制器3个盘创RAID_DP 这样也是比较浪费的。下面介绍如何将系统盘RAID_DP改成RAID_4RAID_4每个控制器只需要2个硬盘。这样的话系统盘由6 块就变成只需要4块就够了。1、查看系统控制器RAID配置信息可以看到目前存储系统是使用3个盘创建RAD_DPFAS2750:: run -node localhost sysconfig -r Aggregate aggr0_FAS2750_01 (online, raid_dp) (block checksums) Plex /aggr0_FAS2750_01/plex0 (online, normal, active, pool0) RAID group /aggr0_FAS2750_01/plex0/rg0 (normal, block checksums) RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- dparity 0b.00.0 0b 0 0 SA:A 0 SAS 10000 1142352/2339537408 1144641/2344225968 parity 0b.00.1 0b 0 1 SA:A 0 SAS 10000 1142352/2339537408 1144641/2344225968 data 0b.00.2 0b 0 2 SA:A 0 SAS 10000 1142352/2339537408 1144641/2344225968 Pool1 spare disks (empty) Pool0 spare disks (empty) Partner disks RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- partner 0b.00.4 0b 0 4 SA:A 0 SAS 10000 0/0 1144641/2344225968 partner 0b.00.5 0b 0 5 SA:A 0 SAS 10000 0/0 1144641/2344225968 partner 0b.00.3 0b 0 3 SA:A 0 SAS 10000 0/0 1144641/23442259682、使用以下命令将系统盘RAID_DP改为RAID_4FAS2750:: aggr modify -aggregate aggr0_FAS2750_01 -raidtype raid43、查看系统控制器RAID配置信息可以看到目前存储系统已经由原来的3个盘RAID_DP变成2个盘的RAID_4FAS2750::run -node FAS2750-01 sysconfig -r Aggregate aggr0_FAS2750_01 (online, raid4) (block checksums) Plex /aggr0_FAS2750_01/plex0 (online, normal, active, pool0) RAID group /aggr0_FAS2750_01/plex0/rg0 (normal, block checksums) RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- parity 0b.00.1 0b 0 1 SA:A 0 SAS 10000 1142352/2339537408 1144641/2344225968 data 0b.00.2 0b 0 2 SA:A 0 SAS 10000 1142352/2339537408 1144641/2344225968 Pool1 spare disks (empty) Pool0 spare disks RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- Spare disks for block checksum spare 0b.00.0 0b 0 0 SA:A 0 SAS 10000 1142352/2339537408 1144641/2344225968 (not zeroed) Partner disks RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- partner 0b.00.4 0b 0 4 SA:A 0 SAS 10000 0/0 1144641/2344225968 partner 0b.00.5 0b 0 5 SA:A 0 SAS 10000 0/0 1144641/2344225968 partner 0b.00.3 0b 0 3 SA:A 0 SAS 10000 0/0 1144641/2344225968
