Изъятие сбойного диска из массива¶
Собираем информацию о диске¶
http://serverfault.com/questions/381177/megacli-get-the-dev-sd-device-name-for-a-logical-drive
Нас интересует 'Target Id' из вывода
megacli -ldinfo -Lall -aall
Virtual Drive: 5 (Target Id: 5) Name :r0-2-ssd
Поставил lshw, сравниваем 'Target Id' и 'bus info':
bus info: scsi@0:2.5.0 logical name: /dev/sdf
Смотрим какой раздел находится на этом диске:
lvs -o +seg_pe_ranges |grep /dev/sdf
ssd-kvm321-chi-slave-db ssd -wi-ao-- 400.00g /dev/sdf:2560-104959
Собираем информацию по "Other Error Count: 1".
megacli AdpEventLog -GetEvents -f megacli.log -a0
Из файла megacli.log:

Смотрим какому виртуальному устройству соответствует сбойный физический диск¶
megacli -LdPdInfo -a0 -nolog

Смотрим массив¶
megacli -LDGetProp -Name -L5 -a0 -nolog
Adapter 0-VD 5(target id: 5): Name: r0-2-ssd Exit Code: 0x00
Выводим диск¶
Разбираем массив¶
megacli -CfgLdDel -L5 -a0 -nolog
Adapter 0: Deleted Virtual Drive-5(target id-5) Exit Code: 0x00
Смотрим физический диск по его Enclosure Device ID и Slot Number - [E:S]¶
megacli -pdInfo -PhysDrv [32:15] -a0 -nolog
Enclosure Device ID: 32 Slot Number: 15 Enclosure position: 1 Device Id: 15 WWN: 5e83a970e3f8ae05 Sequence Number: 3 Media Error Count: 0 Other Error Count: 3 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 PD Type: SATA Raw Size: 447.130 GB [0x37e436b0 Sectors] Non Coerced Size: 446.630 GB [0x37d436b0 Sectors] Coerced Size: 446.625 GB [0x37d40000 Sectors] Sector Size: 0 Firmware state: Unconfigured(good), Spun Up Device Firmware Level: 1.0 Shield Counter: 0 Successful diagnostics completion on : N/A SAS Address(0): 0x500056b36789abdc Connected Port Number: 0(path0) Inquiry Data: OCZ-6R12G0UG3MU5KHK2OCZ-VERTEX460 1.0 FDE Capable: Not Capable FDE Enable: Disable Secured: Unsecured Locked: Unlocked Needs EKM Attention: No Foreign State: None Device Speed: 6.0Gb/s Link Speed: 6.0Gb/s Media Type: Solid State Device Drive: Not Certified Drive Temperature : N/A PI Eligibility: No Drive is formatted for PI information: No PI: No PI Port-0 : Port status: Active Port's Linkspeed: 6.0Gb/s Drive has flagged a S.M.A.R.T alert : No Exit Code: 0x00
1. Перевод в offline (пропускаем)¶
Так как у нас диск в статусе "Firmware state: Unconfigured(good), Spun Up", то переводить его в offline не нужно.
Он был бы в online если бы принадлежал одному из логических дисков.
megacli -PDOffline -PhysDrv [32:15] -a0 -nolog
Adapter: 0: Failed to change PD state at EnclId-32 SlotId-15. Exit Code: 0x01
2. Помечаем диск, как отсутствующий¶
megacli -PDMarkMissing -PhysDrv [32:15] -a0 -nolog
Adapter: 0: Failed to change PD state at EnclId-32 SlotId-15. FW error description: The specified device is in a state that doesn't support the requested command. Exit Code: 0x32
Не сработало. Видимо так и нужно на контроллерах PERC H710P
Mark the drive as missing (seems to not work on R510 H700 card, so just do the next step)

3. Подготавливаем диск к изъятию¶
megacli -PdPrpRmv -PhysDrv [32:15] -a0 -nolog
Prepare for removal Success Exit Code: 0x00
после этого шага меняется: Firmware state: Unconfigured(good), Spun down
4. Включаем подсветку диска¶
megacli -PdLocate -start -PhysDrv [32:15] -a0 -nolog
Adapter: 0: Device at EnclId-32 SlotId-15 -- PD Locate Start Command was successfully sent to Firmware Exit Code: 0x00
5. Изъятие диска¶
6. Проверка, тот ли изъяли¶
megacli -pdinfo -physdrv [32:15] -aall -nolog
Adapter 0: Device at Enclosure - 32, Slot - 15 is not found. Exit Code: 0x00
Все верно
