Description

When a shared Storage Repository configured with iSCSI multipathing shows only one active path in XenCenter, it indicates that only a single iSCSI session is active between the host and the storage target.

When we log in from the command line without specifying a particular target, it does not log in to all available sessions. As a result, only a single active path is shown. However, when we log in using the specific target IP address, the login is successful and both sessions become visible.

In a properly configured multipath environment, multiple paths should be active to provide redundancy and improved performance.

Cause

When Login command is not giving expected result.

Resolution

1. Log in to a specific iSCSI target:

Use this command to log into a particular target session:

iscsiadm -m node -T targetname -p ipaddress -l
 
2. Display all active iSCSI sessions to validate:
 
Use this command to list all current logged-in sessions:
 
iscsiadm -m session
