Dell Unity：数据块导入会话中出现不可恢复的错误

导入 > 会话

x  Import_FNM00104600114_migrate_xxx          Error           block

在上述错误中，将鼠标悬停在红色 X 上会显示更多详细信息：

"The import session failed due to a non-recoverable error.  Go to session properties dialog to check health details and resolution steps in GUI or use UEMCLI command  import/session/element show -detail to check session health details and resolution steps."    

会话详细信息的 UEMCLI 输出显示类似的消息：

spa:~>uemcli /import/session show -detail
1:    ID              = import_65548
      Name            = Import_ABCD1234567890_101_20160915160406.767527+000
      Session type    = block
      Health state    = Critical failure (25)
      Health details  = "The import session failed due to a non-recoverable error. For Block import session non-recoverable error details, check session element's health details and resolution steps."
      State           = Error  ---output abridged----

上述导入会话 ID 的会话元素的 UEMCLI 输出详细信息：

示例 1：

spa:~>uemcli /import/session/element -importId import_65548 show -detail
1:    Source system   = RS_65560
      Source resource = LUN 101
      Target resource = sv_11
      Health state    = Major failure (20)
      Health details  = "Element import session related Sancopy session ran into error: 0x712A8021: The destination device could not be found. This is probably due to incorrect zoning on the switch or the device is not in the correct storage group. (WWN). This can be due to FC Zoning or iSCSI Connection configuration between VNX and Unity arrays. Please follow documentation to configure connectivity between all SP pairs between VNX and Unity system. Once FC/iSCSI connection configuration is validated, please run 'Verify and Update' operation for Remote System connection to VNX to discover/update all configuration changes. Then issue resume operation on the import session to recover session from error state."

示例 2：

spb:~> uemcli /import/session/element -importId import_65600 show -detail
2:    Source system   = RS_65596
      Source resource = block_1
      Target resource = sv_79
      Health state    = Critical failure (25)
      Health details  = "The import session failed due to a non-recoverable failure. Cancel the import session and determine the integrity of the data."

A "Non-recoverable error" 在块导入会话中可能有多种原因，并且可能并不总是永久性的。检查元素详细信息有助于确定问题的根本原因。潜在原因包括：

• iSCSI 连接问题，可以解决并允许会话重新启动
• 源 VNX 阵列上的问题，例如一致性组中缺少 LUN，这可能需要取消会话
• 由于 Unity 阵列上的删除或缺少更新而导致源 LUN 不可用，这也需要取消会话

调查元素详细信息有助于确定原因，并采取适当的措施来解决或取消失败的会话。

如上所述，可能存在不同的问题，导致 'Non-recoverable error' 用于块导入会话。
Unisphere （UI） 可能无法提供足够的详细信息来解决问题。建议使用 UEMCLI 会话元素的输出来对问题进行故障处理和解决。

导入会话失败并显示“不可恢复的错误”：
1.在 UEMCLI 中，确定导入会话 ID：

spb:~> uemcli /import/session/block show -detail
1:    ID                           = import_65600
      Name                         = Import_ABCD1234567890_migrate_20161027142745.428999+000
      Session type                 = block
      Health state                 = Critical failure (25)

2.查看导入会话 ID 的导入会话元素的详细信息：

spb:~> uemcli /import/session/element -importId import_65600 show -detail
1:    Source system   = RS_65596
      Source resource = block_1
      Target resource = sv_79
      Health state    = Critical failure (25)
      Health details  = "The import session failed due to a non-recoverable failure. Cancel the import session and determine the integrity of the data."

3.按照“运行状况详细信息”输出中提供的建议，对导入会话问题进行故障处理和解决。
注意：要继续，请在 UI 中的 “More actions” 下恢复会话。
