New/Migrated LUN are not visible on host due to SLM/portset
Applies to
Issue
- Unable to connect to new LUN
- After volume migartion host not able to access the LUN
- LUN is online, mapped and on the expected node as indicated in System Manager or on CLI
Example:
cluster1::> lun show -path /vol/vol_linux/lun1 -fields vserver,path,state,mapped,node
vserver path state mapped node
--------- ------------------- ------ ------ -----------
svm_linux /vol/vol_linux/lun1 online mapped cluster1-03
- igroup has SLM and portset set
Example:
cluster1::> lun mapping show -path /vol/vol_linux/lun1 -fields vserver,path,igroup,portset,reporting-nodes
vserver path igroup portset reporting-nodes
--------- ------------------- ----------- ------- -----------------------
svm_linux /vol/vol_linux/lun1 linux_iscsi test cluster1-03,cluster1-04
- portset contains LIFs
Example:
cluster1::> portset show
Vserver Portset Protocol Port Names Igroups
--------- ------------ -------- ----------------------- ------------
svm_linux test mixed iscsi_1-1, iscsi_1-2, iscsi_2-1, iscsi_2-2
linux_iscsi
-
LIFs are not on the same nodes that are used for SLM (reporting-nodes)
Example:
cluster1::> net int show -vserver svm_linux -data-protocol iscsi -fields lif,curr-node
(network interface show)
vserver lif curr-node
