监控显示服务器的磁盘故障，查看是插槽0的磁盘有问题，联系机房进行更换，Raid1更换磁盘直接在故障盘的槽位热插拔即可，切记不要拔错了。
服务器：R640
一、查看硬盘信息
megacli -PDList -aAll -NoLog Adapter #0 Enclosure Device ID: 32 Slot Number: 0 Drive's position: DiskGroup: 0, Span: 0, Arm: 0 Enclosure position: 1 Device Id: 0 WWN: 5000C500D213ECE0 Sequence Number: 12 Media Error Count: 0 Other Error Count: 0 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 PD Type: SAS Raw Size: 1.636 TB [0xd196e9b0 Sectors] Non Coerced Size: 1.636 TB [0xd186e9b0 Sectors] Coerced Size: 1.636 TB [0xd1840000 Sectors] Sector Size: 512 Logical Sector Size: 512 Physical Sector Size: 4096 Firmware state: Rebuild Device Firmware Level: ST58 Shield Counter: 0 Successful diagnostics completion on : N/A SAS Address(0): 0x5000c500d213ece1 SAS Address(1): 0x0 Connected Port Number: 0(path0) Inquiry Data: SEAGATE DL1800MM0159 ST58WBN3PQQ0 FDE Capable: Not Capable FDE Enable: Disable Secured: Unsecured Locked: Unlocked Needs EKM Attention: No Foreign State: None Device Speed: 12.0Gb/s Link Speed: 12.0Gb/s Media Type: Hard Disk Device Drive Temperature :24C (75.20 F) PI Eligibility: No Drive is formatted for PI information: Yes PI: PI with type 2 Port-0 : Port status: Active Port's Linkspeed: 12.0Gb/s Port-1 : Port status: Active Port's Linkspeed: 12.0Gb/s Drive has flagged a S.M.A.R.T alert : No Enclosure Device ID: 32 Slot Number: 1 Drive's position: DiskGroup: 0, Span: 0, Arm: 1 Enclosure position: 1 Device Id: 1 WWN: 5000039968186540 Sequence Number: 2 Media Error Count: 0 Other Error Count: 0 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 PD Type: SAS Raw Size: 1.636 TB [0xd196e9b0 Sectors] Non Coerced Size: 1.636 TB [0xd186e9b0 Sectors] Coerced Size: 1.636 TB [0xd1840000 Sectors] Sector Size: 512 Logical Sector Size: 512 Physical Sector Size: 4096 Firmware state: Online, Spun Up Device Firmware Level: EF03 Shield Counter: 0 Successful diagnostics completion on : N/A SAS Address(0): 0x5000039968186542 SAS Address(1): 0x0 Connected Port Number: 0(path0) Inquiry Data: TOSHIBA AL15SEB18EQY EF035950A3KSFQZF FDE Capable: Not Capable FDE Enable: Disable Secured: Unsecured Locked: Unlocked Needs EKM Attention: No Foreign State: None Device Speed: 12.0Gb/s Link Speed: 12.0Gb/s Media Type: Hard Disk Device Drive Temperature :27C (80.60 F) PI Eligibility: No Drive is formatted for PI information: Yes PI: PI with type 2 Port-0 : Port status: Active Port's Linkspeed: 12.0Gb/s Port-1 : Port status: Active Port's Linkspeed: 12.0Gb/s Drive has flagged a S.M.A.R.T alert : No
二、卸载故障盘
megacli -PDOffline -PhysDrv[32:0] -a0
32和0的对应关系
Enclosure Device ID: 32 Slot Number: 0
三、让机房更换磁盘
megacli -PDList -aAll -NoLog Adapter #0 Enclosure Device ID: 32 Slot Number: 0 Drive's position: DiskGroup: 0, Span: 0, Arm: 0 Enclosure position: 1 Device Id: 0 WWN: 5000C500D213ECE0 Sequence Number: 12 Media Error Count: 0 Other Error Count: 0 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 PD Type: SAS Raw Size: 1.636 TB [0xd196e9b0 Sectors] Non Coerced Size: 1.636 TB [0xd186e9b0 Sectors] Coerced Size: 1.636 TB [0xd1840000 Sectors] Sector Size: 512 Logical Sector Size: 512 Physical Sector Size: 4096 Firmware state: Rebuild
查看硬盘正则rebuild,等待变成Online即可。
四、查看rebuild进度
megacli -PDRbld -ShowProg -PhysDrv[32:0] -aAll Rebuild Progress on Device at Enclosure 32, Slot 0 Completed 28% in 34 Minutes. Exit Code: 0x00
五、检查磁盘rebuild后是否在线的状态
megacli -PDList -aAll -NoLog | grep 'Firmware state' Firmware state: Rebuild Firmware state: Online, Spun Up
当Firmware state 变成Online, Spun Up 就已经rebuild结束。
