一、前言
最近遇到一個(gè)需求，公司有套NetAPP存儲(chǔ)已過保一段時(shí)間，目前作為測(cè)試環(huán)境使用，但最近這套存儲(chǔ)出現(xiàn)故障，一條鏈路狀態(tài)異常。導(dǎo)致其上配置的多路徑有兩條鏈路非Active狀態(tài)，系統(tǒng)組擔(dān)心會(huì)影響到數(shù)據(jù)庫的使用。最近剛好有套過保的3par存儲(chǔ)，在配置和性能方面都要優(yōu)于這套過保的NetAPP存儲(chǔ)，希望我配合進(jìn)行存儲(chǔ)的替換。
目前這套NetAPP存儲(chǔ)，數(shù)據(jù)庫組目前在其上部署的有4套環(huán)境，其中有三套都是單機(jī)在使用，可以方便替換，其中有套Oracle 19C RAC測(cè)試庫，雖然是測(cè)試庫，但當(dāng)前生產(chǎn)對(duì)應(yīng)的很多測(cè)試都是在其上進(jìn)行驗(yàn)證測(cè)試，非常重要，需要提前和項(xiàng)目組溝通，并要避免數(shù)據(jù)的丟失和損壞。
之前我曾驗(yàn)證過EMC存儲(chǔ)和3Par存儲(chǔ)的替換，因?yàn)镋MC日常使用的是EMC自帶的存儲(chǔ)，3Par存儲(chǔ)通常使用操作系統(tǒng)自帶multipah多路徑軟件，在同一臺(tái)服務(wù)器上安裝時(shí)會(huì)有不兼容的情況。
但目前這套NetAPP使用的multipah多路徑軟件,和3par還是可以兼容的。
為防止在替換過程中會(huì)出現(xiàn)一些意外，我這邊還是提前做了一些相關(guān)備份操作，將多路徑軟及OCR信息進(jìn)行了手工備份，并將數(shù)據(jù)庫數(shù)據(jù)進(jìn)行了備份。
并通知了項(xiàng)目組，計(jì)劃在下班后進(jìn)行操作。
二、環(huán)境信息
這套19C RAC庫操作系統(tǒng)為Centos 7.9，當(dāng)前存儲(chǔ)使用3個(gè)多T。

然后通知系統(tǒng)管理員為這套R(shí)AC 分配3Par存儲(chǔ)。為何原存儲(chǔ)進(jìn)行區(qū)分，新分配的存儲(chǔ)沒塊大小都和之前不同，便于區(qū)分，存儲(chǔ)分配后，先逐臺(tái)重啟了兩臺(tái)數(shù)據(jù)庫服務(wù)器識(shí)別到新加的存儲(chǔ)。
然后使用dd if=/dev/zero of=/dev/mapper/xxx bs=1024k count=10000 對(duì)新加的存儲(chǔ)進(jìn)行格式化，然后進(jìn)行fdisk分區(qū)。
之后通過如下oracleasm命令創(chuàng)建新的ASM磁盤，新創(chuàng)建的ASM磁盤名稱和原磁盤名稱區(qū)分開來。
[root@local-test-xxxx~]# oracleasm createdisk VOL1 /dev/mapper/mpathi1
[root@local-test-xxxx~]# oracleasm createdisk VOL2 /dev/mapper/mpathj1
[root@local-test-xxxx~]# oracleasm createdisk VOL3 /dev/mapper/mpathk1
[root@local-test-xxxx~]# oracleasm createdisk VOL4 /dev/mapper/mpathl1
[root@local-test-xxxx~]# oracleasm createdisk VOL5 /dev/mapper/mpathm1
---然后再二個(gè)節(jié)點(diǎn)掃盤識(shí)別到新加的ASM存儲(chǔ)盤。
[root@local-test-xxxx2 ~]# oracleasm scandisks
三、磁盤替換
對(duì)于數(shù)據(jù)盤替換，這塊之前已經(jīng)做了好多次，心里有把握，現(xiàn)將新的ASM磁盤通過如下方式添佳到數(shù)據(jù)磁盤組：
su - grid
sqlplus /as sysasm
SQL> alter diskgroup DG add disk '/dev/oracleasm/disks/VOL4' rebalance power 11;
SQL> alter diskgroup DG add disk '/dev/oracleasm/disks/VOL5' rebalance power 11;
SQL> SQL> select * from v$asm_operation;
2 REBAL COMPACT WAIT 11 11 0 0 0 0 0
2 REBAL REBALANCE RUN 11 11 5962 71713 3900 16 0
2 REBAL REBUILD DONE 11 11 0 0 0 0
替換OCR盤，之前替換10G RAC OCR盤的時(shí)候比較麻煩，需要修改的配置較多，但替換19C OCR盤還是第一次，心里也是沒有把握，于是查詢了網(wǎng)上一些資料，看到JikeXu曾寫過 11g https://cloud.tencent.com/developer/article/1696479 OCR替換，不知道19C是不是也可以，并向其進(jìn)行了請(qǐng)教。
SQL> alter diskgroup CRS add disk '/dev/oracleasm/disks/VOL1';
alter diskgroup CRS add disk '/dev/oracleasm/disks/VOL1'
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15410: Disks in disk group CRS do not have equal size.
因?yàn)樾碌腛CR盤和原盤大小不同，無法直接添加，恩墨彗星性老師給我一個(gè)他曾寫的文章：http://m.sunline.cc/db/543611 對(duì)于ORA-15410 Disks in disk group OCR_VOT do not have equal size 有相應(yīng)的解釋和處理辦法。我本次沒有去嘗試。
于是決定采用JiekeXU提到的方法將全部OCR添加進(jìn)去并替換掉原有的OCR盤。
su - grid
sqlplus / as sysasm
