Symptoms

  • 執行狀況檢查指令檔 （proactive_check.pl） 無法確定節點的硬體類型： 
cat hc_results.txt

...
WARNING:  Node (0.2) Unknown node type based on disk size (5 TB), memory (32 GB) and disk partitions (3)
RESOLUTION: Thoroughly check hardware status, size of partitions, number of partitions and amount of memory

# --> Node Type                      *FAILED*
# --> Node Type                       1x4 gen4s-Util/Accel, gen4s-M1200, Unknown 5 TB<snip>
 
  • 受影響的節點上的硬體命令失敗： 
avsysreport chassis-info

sudo: /etc/sudoers is mode 0551, should be 0440
sudo: no valid sudoers sources found, quitting 

Cause

權限 /etc/sudoers 檔案不正確。

Resolution

1.以系統管理員身分登入 Avamar 工具節點。 

2.提升至 root，然後載入 ssh keys。請參閱 Avamar：如何登入 Avamar Server 並載入各種金鑰 ，以取得更多資訊。

3.檢查權限 /etc/sudoers 所有節點的檔案： 

mapall --noerror --all+ --user=root 'ls -ahltr /etc/sudoers'
 

單節點網格的預期輸出： 

Using /usr/local/avamar/var/probe.xml
(0.0) ssh -q  -x  -o GSSAPIAuthentication=no root@10.10.10.246 'ls -ahltr /etc/sudoers'
-r--r----- 1 root root 9.9K Aug 25 22:53 /etc/sudoers
 

多節點網格的預期輸出：

Using /usr/local/avamar/var/probe.xml
(0.s) ssh -q  -x  -o GSSAPIAuthentication=no root@192.168.255.1 'ls -ahltr /etc/sudoers'
-r--r----- 1 root root 8.3K Aug 17  2023 /etc/sudoers
(0.0) ssh -q  -x  -o GSSAPIAuthentication=no root@192.168.255.2 'ls -ahltr /etc/sudoers'
-r--r----- 1 root root 9.8K Jun  1  2022 /etc/sudoers
(0.1) ssh -q  -x  -o GSSAPIAuthentication=no root@192.168.255.3 'ls -ahltr /etc/sudoers'
-r--r----- 1 root root 9.8K Jun  1  2022 /etc/sudoers
(0.2) ssh -q  -x  -o GSSAPIAuthentication=no root@192.168.255.4 'ls -ahltr /etc/sudoers'
-r--r----- 1 root root 9.8K Jun  1  2022 /etc/sudoers
 

4.對於報告權限或擁有權不正確的任何節點：

一個。連線至有問題的節點。

b.視需要修改權限或擁有權：

chmod 440 /etc/sudoers
chown root:root /etc/sudoers
 

c. 驗證硬體命令是否正確回應：

avsysreport chassis-info

=== Chassis information
Host Name     : testavamar.company.com
Chassis Model : Gen4S M1200
Serial Number : FC6AV123456789
Part Number   : 100-580-643
BIOS Version  : SE5C600.86B.02.04.0003.102320141138
 

執行狀況檢查指令檔現在應會在不報告警示的情況下執行。
