PowerScale Gen6/MLK 節點無法開機，GEOM 啟動失敗

將節點因任何原因重新開機時，節點無法重新連線。如果使用零數據機電纜連接到節點，則引導序列將以類似於以下內容的消息結束：

kldload: acpi_sel0: <System Error Log (SEL) GPE Hook> numa-domain 0 on acpi0

如果您進入復原 Shell 並檢查已掛接的檔案系統，root 會掛載為唯讀：

# mount
/dev/mirror/root1 on / (ufs, local, read-only)
devfs on /dev (devfs, local)
#

檢查開機磁碟分割，您會看到類似以下內容：

# gpart list | grep -B9 bootdisk | egrep "uuid|Name|label"|paste - - -

4. Name: da17p4    rawuuid: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx           label: bootdiskid
4. Name: da18p4    rawuuid: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx           label: bootdiskid

4. Name: da21p4    rawuuid: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx           label: bootdiskid
2. Name: ada0p2    rawuuid: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx           label: bootdiskid

ada0 上的開機分割區無效。Gen6/MLK 節點不應在該裝置上具有開機分割區。
