SMO 或 SMSAP 无法删除 Windows 中的备份，引用的驱动器号不存在
适用场景
- Windows 上的 SnapManager for Oracle （ SMO ） 3.4.x
- Windows 上的 SnapManager for SAP （ SMSAP ） 3.4.x
问题描述
运行备份保留时，无法删除旧备份，因为驱动器号挂载点路径上存在 SnapDrive 错误，例如，从事件日志中：
Failed to delete the Snapshot copy (smsap_<SID>_f_h_2_<UUID>_0) of the LUN (X:\ORACLE\<SID>\ORAARCH)
on storage system (<SVM>) volume (<FLEXVOL>).
Error code : The LUN may not be connected, because its mount point cannot be found.
在 SnapManager 报告日志（ SMO_O_of_* 。 log/smsap_of_* 。 log ）中：
SD-00015: Error deleting snapshot(s): SD-10016: Error executing snapdrive command "snap delete :/vol/<ORAARCH_VOLUME>:smsap_<SID>_f_h_1_<UUID>_0": The LUN may not be connected, because its mount point cannot be found,
SD-00015: Error deleting snapshot(s): SD-10016: Error executing snapdrive command "snap delete :/vol/<ORAARCH_VOLUME>:smsap_<SID>_f_h_2_<UUID>_0": The LUN may not be connected, because its mount point cannot be found
