Only 1 path active on XS which is part of the pool
While creating new SR on XS 6.0.2 on EMC VNX 5300 will show one host with 1 active path rest all have all the active path . When multipath -ll is run it will also show one path . This shows that all the path is not having access to the lun .
From the host which has an issue logoff all the active path
iscsiadm -m node -U all and then logback in iscsiadm -m node -L all.
Restart the multipathd service /etc/init.d/multipathd restart. This will bring all the path active on the host.
