LSISAS1068E SAS Controller

今天在管理的機器有 HDD 出了問題，所以 HWRAID 就自動重 build. 因為好奇所以想進去看了一下RAID card 型號，結果發現是不認識的東西，用 megacli 也不能操作. 查了一下， 發現是很久以前的 LSI SAS CHIP 是 SATA 

$ lspci | grep LSI
01:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08)

http://www.lsi.com/products/storagecomponents/Pages/LSISAS1068E.aspx
＊ 8-port SAS/SATA Controller
＊ Supports 1.5 and 3Gb/s SAS and SATA data transfer rates per port, full duplex
＊ Integrated RAID support （Only RAID0 and RAID1)

第一個操作的工具可以快速的看到目前 RAID 的狀態, 可以 state 是 "DEGRADED", 正常會是 "OPTIMAL"

$ mpt-status 
ioc0 vol_id 0 type IME, 8 phy, 1862 GB, state DEGRADED, flags ENABLED RESYNC_IN_PROGRESS
ioc0 phy 9 scsi_id 9 ATA      ST9500530NS      DA03, 465 GB, state ONLINE, flags NONE
ioc0 phy 8 scsi_id 1 ATA      ST9500530NS      DA03, 465 GB, state ONLINE, flags NONE
ioc0 phy 7 scsi_id 2 ATA      ST9500530NS      DA03, 465 GB, state ONLINE, flags NONE
ioc0 phy 0 scsi_id 8 ATA      ST9500530NS      DA03, 465 GB, state ONLINE, flags OUT_OF_SYNC
ioc0 phy 5 scsi_id 3 ATA      ST9500530NS      DA03, 465 GB, state ONLINE, flags NONE
ioc0 phy 4 scsi_id 5 ATA      ST9500530NS      DA03, 465 GB, state ONLINE, flags NONE
ioc0 phy 3 scsi_id 4 ATA      ST9500530NS      DA03, 465 GB, state ONLINE, flags NONE
ioc0 phy 2 scsi_id 6 ATA      ST9500530NS      DA03, 465 GB, state ONLINE, flags NONE

如果要看更多的資訊，可以用 lsiutil, 操作上是採用 interactive mode.

$ lsiutil
