怎樣修改instance number?

lu407

修改instance number對(duì)于安裝系統(tǒng)和mc來(lái)說(shuō)有一定作用。。再說(shuō)因?yàn)樵��?jīng)的case印象深刻。。

1.  Extract a configuration template from the current ioscan output.
         Execute the following command:

         # ioscan -f | grep -e INTERFACE -e DEVICE | \
         grep -v target | \
         awk '{print $3, $1, $2}' > /infile

     2.  Edit /infile and change the ext_bus and lan instances as desired.
         No class is allowed to get more than one line for the same instance!

     3.  Bring down the system gracefully to run level 1.

         # init 1

     4.  Apply the ioconfig change:

         # /sbin/ioinit -f /infile -r

         The system will reboot immediately if the change is successful.
         Warnings like 'Input is identical to kernel' can be ignored.

         If unsuccessful, the most likely error to happen is:
         "ioinit: Instance number X already exists for class XXX"

         The problem is that your desired instance assignment conflicts with
         an existing instance number.

     5.  Once the system reboots, verify that all the instance numbers
         were changed as expected. It may be necessary to re-import volume
         groups to ensure that /etc/lvmtab contains the correct
         entries. The lan configuration may need to be changed also.

修改實(shí)例個(gè)數(shù)？
是在你的數(shù)據(jù)庫(kù)安裝好了吧？
可以通過(guò)srvctl 來(lái)實(shí)現(xiàn)的，你參考：

希望對(duì)你有用！

汗。�？磥�(lái)兄弟們對(duì)這個(gè)不是很熟悉
修改instance number的作用是用來(lái)修改設(shè)備文件名。。比如一個(gè)disk本來(lái)叫c0t6d0通過(guò)修改使之變成c2t6d0。。
因?yàn)閕nstance number本來(lái)是系統(tǒng)自身分配的。。很多情況下要求雙機(jī)設(shè)備文件名一致，可以通過(guò)以上方法修改。。
當(dāng)然這是最簡(jiǎn)單的一種。。

頂！言簡(jiǎn)意賅！收藏！

看來(lái)以后共享文檔還是寫(xiě)成中文的比較好。。

哈哈，此“實(shí)例”非彼“實(shí)例”�。�
一個(gè)是HP設(shè)備的稱呼
一個(gè)是Oracle的叫法！
呵呵
