SCO 验证作业会在 /etc/systemd/system/ but 中创建到 /dev/null 的符号链接 不会将其删除

适用于

• 适用于 Oracle 数据库（ SCO ）的 SnapCenter 插件 4.3 ， 4.4
• SAN 或 VMDK 配置

问题

• 运行 SCO 验证作业时，系统会在 /etc/systemd/system 中创建指向 /dev/null 的符号链接（符号链接），但不会自动将其删除。
• 符号链接的名称包含 "var-opt-snapcenter-sco-backup_verify" ，如以下示例所示。

示例：

[root@rhel2 system]# ls -l /etc/systemd/system/var-opt-snapcenter-sco-backup_*
lrwxrwxrwx 1 root root 9 Dec  9 02:04 /etc/systemd/system/var-opt-snapcenter-sco-backup_verify-rhel2_demo_netapp_com_orcl_rhel2_12-09-2020_02.02.15.6102_0-orcl-1.mount -> /dev/null
lrwxrwxrwx 1 root root 9 Dec  9 02:11 /etc/systemd/system/var-opt-snapcenter-sco-backup_verify-rhel2_demo_netapp_com_orcl_rhel2_12-09-2020_02.09.00.3082_0-orcl-1.mount -> /dev/null
lrwxrwxrwx 1 root root 9 Dec  9 02:30 /etc/systemd/system/var-opt-snapcenter-sco-backup_verify-rhel2_demo_netapp_com_orcl_rhel2_12-09-2020_02.28.05.0975_0-orcl-1.mount -> /dev/null
 

• spl_<verification_job_id>.log 表示已执行 SCO systemctl mask以创建符号链接。
