Listing LUNs Takes Over a Minute on M6-32 Servers (18125373)

On M6-32 servers, the listing of LUNs by using commands such as format and mpathadm list lu takes more time because of the cache invalidation by an unknown thread. Whenever a command is executed to list LUNs, a fresh snapshot of LUNs is generated due to the zeroed cache, which causes a delay in listing the LUNs.

Workaround: Perform the following steps on the iSCSI Initiator:

  1. Remove the links to LUNs that are not accessible.

    # devfsadm -Cv
  2. Remove the discovery address of the unreachable iSCSI target host.

    # iscsiadm remove discovery-address target-address
