例:

[cluster2-02: BcomkaThr_04: scsiblade.lun.ids.change:error]: A change in identifiers of a LUN in Vserver SVM02 and volume with MSID 2159662485 has been detected. The previous and new serial numbers are '81KMn?Uiv7-6', '81KEr]Uivwzi'. The previous and new UUIDs are '8b21a58d-e9a1-4621-8a59-3d79af19a688', 'bb1bd76b-ed08-4910-a177-3e63d7cd8713'. The previous and new device text IDs are '', ''. The previous and new device binary IDs are '', ''. Other LUNs on this volume are also affected.
  • lun show コマンドは、新しいシリアル番号と新しいUUIDを表示します。

例:

cluster2::*> lun show -fields uuid
vserver path       uuid                  
------- -------------- ------------------------------------ 
SVM02   /vol/dest/lun0 bb1bd76b-ed08-4910-a177-3e63d7cd8713 

 
  • ただし、には lun mapping show 以前のUUIDが引き続き表示されます。

例:

cluster2::*> lun mapping show -fields lun-uuid
vserver path       igroup   lun-uuid                
------- -------------- -------  ---------------------------------- 
SVM02   /vol/dest/lun0 DB1       8b21a58d-e9a1-4621-8a59-3d79af19a688 
SVM02   /vol/dest/lun0 DB2    8b21a58d-e9a1-4621-8a59-3d79af19a688 
  • SANホストは以前のシリアル番号を認識します。

例:

# multipath -ll
