WAFL_Check 和 WAFLRon 如何与集群模式 Data ONTAP 8 中的 SnapMirror 目标卷交互？
适用场景
- 集群模式 Data ONTAP 8.2
- 集群模式 Data ONTAP 8.1
- 集群模式 Data ONTAP 8
- ONTAP 9
问题解答
WAFL_Check 或 WAFLIRON 是否可以在包含 SnapMirror 目标卷的聚合上运行？
有关 WAFL_Check 和 Wafliron 的详细信息，请参见以下知识库文章。
注：从 Data ONTAP 8.1 开始、 WAFL_Check 已从启动菜单中删除、不再是受支持的操作。将改用 wafliron 和 wafliron 可选的提交。
负载共享 SnapMirror 目标卷
WAFL_Check 和 Wafliron 将跳过负载共享 SnapMirror 目标卷。Wafliron 对负载共享 SnapMirror 目标卷的尝试示例：
在诊断模式下运行命令
Node1::>set diag
Node1::*>storage aggregate wafliron start -aggregate ls_aggr_1
WARNING: Aggregate ls_aggr_1 contains 1 Load Sharing SnapMirror destination volume(s). If you want to fix inconsistencies on a Load Sharing SnapMirror destination volume, please delete, recreate and resynchronize from the source. Wafliron will skip Load Sharing SnapMirror destination volume(s). Do you still want to continue? {y|n}:
WAFL_Check 针对负载共享镜像目标的尝试示例（将记录到 EMS 日志文件中）：
Skipping Clustered replica volume @vserver (mirror type drm)
数据保护 SnapMirror 目标卷
默认情况下， WAFL_Check 将检查数据保护 SnapMirror 目标卷。Wafliron 将要求在-include-mirrors启动数据保护 SnapMirror 目标卷之前使用选项“”设置为“ true ”。
Wafliron 在未将选项 "-include-mirrors" 设置为 "true" 的情况下试图攻击数据保护 SnapMirror 目标卷的示例：
Node1::*>storage aggregate wafliron start -aggregate dr_aggr_1
WARNING: Aggregate dr_aggr_1 contains 1 Data Protection SnapMirror destination volume(s). You have chosen to skip wafliron on Data Protection SnapMirror destination volume(s). If you want to fix inconsistencies on a Data Protection SnapMirror destination volume, you must use the option '-includemirrors' set to 'true'. Do you still want to continue? {y|n}:
wafliron 尝试使用选项 '-include-mirrors' set to 'true' 来保护 SnapMirror 目标卷的示例。
Node1::*>storage aggregate wafliron start -aggregate dr_aggr_1 -include-mirrors true
WARNING: Aggregate dr_aggr_1 contains 1 Data Protection SnapMirror destination volume(s). You have chosen wafliron to fix inconsistencies by breaking the mirror relationship(s) on the Data Protection SnapMirror destination volume(s). Do you still want to continue? {y|n}: y Initiated wafliron-start on aggregate dr_aggr_1.
数据保护 SnapMirror 目标卷 - VLDB 和 WAFL 重新同步和 SnapMirror 关系重新同步
请注意，在处理完数据保护 SnapMirror 目标卷后、 SnapMirror 关系将处于“删除”状态、 VLDB 和 WAFL 将会出现与目标 SnapMirror 卷有关的不一致信息。
将运行 vReport show 、 vReport fix 和 SnapMirror resync 以继续使用 SnapMirror 关系。
以下是步骤：
Node1::>set diag
Node1::*>debug vreport show -instance
Object type: volume
Object: vserver: dst_vol1
List of attributes: Node Name: Node1
Volume DSID: 1048 MSID:2147484688
UUID: 29ad55c0-5c31-11de-9d1b-123475882448
Aggregate Name: dr_aggr_1
Aggregate UUID: 9k2dc7b0-5c49-11de-acb0-00a5882448f
Vserver UUID: 237328fa-1998-11de-8219-12345882448
AccessType: READ_WRITE
StorageType: REGULAR
StripeType: FLEX_VOL
Reason for difference: Present both in VLDB and WAFL with differences
Duplicate Object Values:
Attributes With Differing Values: Volume Access Type
Values In WAFL: READ_WRITE
Values In VLDB: DP_READ_ONLY
Node1::*>debug vreport fix -type volume -object vserver:dst_vol1
Node1::*>set admin
Node1::>snapmirror resync -destination-path cluster_name://vserver/dst_vol1
现在，目标聚合将保持 WAFL 一致、 SnapMirror 关系将重新同步并再次正常工作
