Table 38. Troubleshooting (continued)
Problem Cause Solution
SMI-S is not responding to
client requests.
SMI-S configuration
may have become
corrupted.
Use the CLI command reset smis-configuration. For more
information, see the Dell EMC PowerVault ME4 Series Storage
System CLI Guide.
Using SLP
ME4 Series storage systems support Service Location Protocol (SLP, srvloc), which is a service discovery protocol that allows
computers and other devices to find services in a LAN without prior configuration. SLP is open for use on all operating systems,
and does not require formal licensing.
SLP is based on User Datagram Protocol (UDP) and can use Transmission Control Protocol (TCP) if needed. SLP listens on port
427. When a client, or User Agent (UA), connects to a network, the client queries for Directory Agents (DA) on the network. If
no DA responds, the client assumes a DA-less network and sends a multicast UDP query. All Service Agents (SA) that contain
query matches will send a UDP answer to the client. If the answer message is too large, the client can repeat the query using
TCP.
In a network with DAs, each SA must register all services with a DA. Then the clients will query the DAs, who will respond to the
query with its cached SA information.
Through use of DAs, SLP can also scale beyond the local area network to large enterprise, which is an enterprise IT issue.
Consult the IETF RFC2165.
When SLP is enabled, the storage system will advertise the interfaces shown in Interfaces advertised by SLP on page 171 and
populate the configuration attributes shown in SLP attributes shown for a storage system on page 171.
You can enable or disable the SLP service in the PowerVault Manager, as described in Enable or disable system-management
settings on page 46, or by using the CLI set protocols command, as described in the Dell EMC PowerVault ME4 Series
Storage System CLI Guide.
If the SLP service is enabled, you can test it by using an open source tool, such as slptool from www.openslp.org.
