如何修改法定裝置節點清單
您可以使用 scsetup(1M) 公用程式，在現有法定裝置的節點清單中增加或移除節點。若要修改法定裝置的節點清單，您必須移除法定裝置、修改節點與要移除的法定裝置之間的實體連接，然後再次新增法定裝置到叢集配置。在增加法定裝置後，scconf(1M) 會自動為所有連結到磁碟的節點配置節點至磁碟的路徑。
-
成為叢集上任何節點的超級使用者。
-
確認您要修改的法定裝置名稱。
# scconf -p | grep Quorum
-
輸入 scsetup 公用程式。
# scsetup
顯示 Main Menu。
-
請鍵入 1 (法定) 以使用法定裝置。
顯示 Quorum Menu。
-
請鍵入 2 (移除法定磁碟) 以移除法定裝置。
依照指示進行。系統會要求您輸入要移除的磁碟名稱。
-
新增或刪除到法定裝置的實體節點連線。
-
請鍵入 1 (新增法定磁碟) 以新增法定裝置。
依照指示進行。系統會要求您輸入用來作為法定裝置的磁碟名稱。
-
確認法定裝置新增成功。
# scstat -q
範例—修改法定裝置節點清單
以下範例顯示如何使用 scsetup 公用程式在法定裝置節點清單上新增或移除節點。在這個範例中，法定裝置名稱為 d2，而此程序的最後結果是新增另一個節點到法定裝置節點清單。
[Become superuser on any node in the cluster.]
[Determine the quorum device name:]
# scconf -p | grep Quorum
Quorum devices: d2
Quorum device name: d2
Quorum device votes: 1
Quorum device enabled: yes
Quorum device name: /dev/did/rdsk/d2s2
Quorum device hosts (enabled): phys-schost-1 phys-schost-2
Quorum device hosts (disabled):
[Execute the utility:]
# scsetup
Type 1 (Quorum).
Type 2 (Remove a quorum disk).
Answer the questions when prompted.
You Will Need: Example:
quorum device name d2
[Verify that the scconf command completed successfully:]
scconf -r -q globaldev=d2
Command completed successfully.
Type 1 (Quorum).
Type 1 (Add a quorum disk).
Answer the questions when prompted.
You Will Need: Example:
quorum device name d2
[Verify that the scconf command completed successfully:]
scconf -a -q globaldev=d2
Command completed successfully.
Quit the scsetup utility.
[Verify that the correct nodes have paths to the quorum device.
In this example, note that phys-schost-3 has been added to the
enabled hosts list.]
# scconf -p | grep Quorum
Quorum devices: d2
Quorum device name: d2
Quorum device votes: 2
Quorum device enabled: yes
Quorum device name: /dev/did/rdsk/d2s2
Quorum device hosts (enabled): phys-schost-1 phys-schost-2
phys-schost-3
Quorum device hosts (disabled):
[Verify that the modified quorum device is online.]
# scstat -q
-- Quorum Votes by Device --
Device Name Present Possible Status
----------- ------- -------- ------
Device votes: /dev/did/rdsk/d2s2 1 1 Online
[Verify the quorum device is removed:]
# scstat -q
-- Quorum Summary --
Quorum votes possible: 4
Quorum votes needed: 3
Quorum votes present: 4
-- Quorum Votes by Node --
Node Name Present Possible Status
--------- ------- -------- ------
Node votes: phys-schost-1 1 1 Online
Node votes: phys-schost-2 1 1 Online
-- Quorum Votes by Device --
