Symptoms

遠端 SupportAssist 集合無法使用偵錯選項匯出。 
[root@server]# racadm -r %idrac% -u %user% -p %password% -d supportassist collect -t Debug -f TSR.zip
Security Alert: Certificate is invalid - self signed certificate in certificate chain
Continuing execution. Use -S option for racadm to stop execution on certificate-related errors.

Cause

選取除錯選項後，其他檔案會新增到集合中。這可能會導致集合達到最大 30 MB 的大小。當集合以最大大小進行遠端提取時，可能會導致 system-httpd.slice 超過最大記憶體。因此，系統會回收 cgroup 中的進程以回到記憶體限制以下，並導致收集失敗。

Resolution

未來的 iDRAC9 韌體 7.20.10.50 會自動清理舊的核心檔案，以減少除錯集合大小。

使用下列其中一個選項匯出偵錯 SupportAssist 集合。

選項 1
在提取遠端集合之前，可以先刪除核心檔以減小集合大小。  
$ racadm -r %idracip% -u %user% -p %password% coredump 
$ racadm -r %idracip% -u %user% -p %password% coredumpdelete -f %filename%
$ racadm -r %idracip% -u %user% -p %password% coredumpdelete --all
選項 2
您可以使用本機 racadm，從主機系統在本機提取偵錯的 SupportAssist 集合。使用此方法不會受到影響，因為它不會在與遠端 racadm 相同的 cgroup 記憶體限制下執行。  
$ racadm supportassist collect -t debug -f TSR.zip
