Example:
[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.- The
lun showcommand displays a new serial number and new UUID.
Example:
cluster2::*> lun show -fields uuid
vserver path uuid
------- -------------- ------------------------------------
SVM02 /vol/dest/lun0 bb1bd76b-ed08-4910-a177-3e63d7cd8713 - However, the
lun mapping showstill shows the previous UUID.
Example:
cluster2::*> lun mapping show -fields lun-uuid
vserver path igroup lun-uuid

SVM02 /vol/dest/lun0 DB2 8b21a58d-e9a1-4621-8a59-3d79af19a688 - SAN host sees the previous serial numbers.
