Segue\u00a0um How to para alterar um disco no exadata (Predictive Failure))<\/p>\n
1- Encontre o disco que deve ser alterado.<\/p>\n
Normalmente a oracle envia no SR\u00a0 um texto assim:<\/p>\n
Slot Number: 6
\nDrive’s postion: DiskGroup: 6, Span: 0, Arm: 0
\nEnclosure position: 0
\nDevice Id: 9
\nWWN: 5000CCA267226EC7
\nSequence Number: 2
\nMedia Error Count: 83 <<<<<<<<<<<<<<<<<
\nOther Error Count: 187 <<<<<<<<<<<<<<<<<<<<<<<<
\nPredictive Failure Count: 0
\nLast Predictive Failure Event Seq Number: 0
\nPD Type: SAS<\/p>\n
Para encontra o ID do disco que sera alterado execute o comando na cell do exadata:<\/p>\n
cellcli\r\n\r\nLIST PHYSICALDISK WHERE diskType=HardDisk<\/pre>\nAp\u00f3s o comando aparecer o disco que esta no\u00a0Slot\u00a0 6 , verifique o disco\u00a0 com o comando abaixo:<\/p>\n
[root@dbm0celzm01 ~]# cellcli -e list physicaldisk 252:6 detail\r\nname: 252:6\r\ndeviceId: 9\r\ndeviceName: \/dev\/sdi\r\ndiskType: HardDisk\r\nenclosureDeviceId: 252\r\nerrOtherCount: 187\r\nluns: 0_6\r\nmakeModel: \"HGST H7210A520SUN010T\"\r\nphysicalFirmware: A3Y1\r\nphysicalInsertTime: 2019-04-11T16:00:07-03:00\r\nphysicalInterface: sas\r\nphysicalSerial: RLY17N\r\nphysicalSize: 8.91015625T\r\nslotNumber: 6\r\nstatus: normal<\/pre>\n<\/p>\n
Tambem \u00e9 possivel encontar os discos que ser\u00e3o alterados no ASM com o comando:<\/p>\n
[root@dbm0celzm01 ~]# cellcli -e list celldisk where lun=0_6 detail\r\nname: CD_06_dbm0celadm01\r\ncomment:\r\ncreationTime: 2019-04-15T17:27:54-03:00\r\ndeviceName: \/dev\/sdi\r\ndevicePartition: \/dev\/sdi\r\ndiskType: HardDisk\r\nerrorCount: 78\r\nfreeSpace: 0\r\nid: 3189d1d9-c8b9-42df-bc32-544d16541a0f\r\nphysicalDisk: RLY17N\r\nsize: 8.9094085693359375T\r\nstatus: normal<\/pre>\nVerifique no ASM\u00a0 se o disco que sera alterado antes de iniciarmos:<\/p>\n
select group_number,path,header_status,mount_status,name from V$ASM_DISK where path like '%CD_06_dbm0celzm01';<\/pre>\nj\u00e1 temos o disco que necessita ser alterado<\/p>\n
agora vamos continuar o procedimento.<\/p>\n
2-\u00a0Em celcli\u00a0execute o comando:<\/p>\n
ALTER PHYSICALDISK 252:6 DROP FOR REPLACEMENT<\/pre>\nEsse comando demora em torno de 50 a 60 minutos divido a realizar\u00a0 todos os passos para\u00a0 remo\u00e7\u00e3o do disco.Ex..Retira disco do ASM,apaga a parti\u00e7\u00e3o e etc..<\/p>\n
Verifique no ASM se o disco foi retirado.<\/p>\n
select group_number,path,header_status,mount_status,name from V$ASM_DISK where path like '%CD_06_dbm0celzm01';<\/pre>\nComo esse comando finalizar o disco que ser\u00e1 trocado ficara com um Led azul<\/p>\n
ap\u00f3s retira o disco ,espere 5 minutos para colocar o novo disco no local.<\/p>\n
com o novo disco j\u00e1 adicionado ,continue os passos.<\/p>\n
3- Ap\u00f3s execute um validate nos discos:<\/p>\n
alter cell validate configuration<\/pre>\n4-Acompanhe no ASM ate a finaliza\u00e7\u00e3o do rebalance do disco<\/p>\n
