问题描述
- EMS报告scsiblade.lun.ids.change:error。
示例：
[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.- 此
lun show命令将显示新的序列号和新UUID。
示例：
cluster2::*> lun show -fields uuid
vserver path uuid
------- -------------- ------------------------------------
SVM02 /vol/dest/lun0 bb1bd76b-ed08-4910-a177-3e63d7cd8713 - 但是、
lun mapping show仍会显示先前的UUID。
示例：
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主机看到以前的序列号。
