Trouble Accessing Exports When Server And Client Configurations Are Correct; Checking Client Access - IBM Storwize V7000 Unified Problem Determination Manual

Trouble accessing exports when server and client
configurations are correct
About this task
If you cannot access an export and the server and client configurations are correct,
it could be because of the following reasons.
v If Storwize V7000 Unified authentication is configured against an LDAP server,
v If Storwize V7000 Unified authentication is configured against an Active

Checking client access

Verify that your client workstation can successfully ping the full host name of the
cluster and all of the IP addresses that are associated with it.
About this task
The following example shows how to ping an cluster. When the client connects to
the host name of the cluster, the DNS server responds with IP addresses. You must
then ping each IP address from the client machine.
If clients cannot successfully ping the IP addresses, then they are not able to access
Storwize V7000 Unified whenever the DNS returns the IP address on name
resolution requests. This can cause some clients have access while others do not.
Procedure
1. To obtain the IP addresses of your Storwize V7000 Unified cluster, issue the
2. Ping each IP address that id listed in the output by issuing the ping returned IP
the user entries are case-sensitive when you access exports . If the server and
client configurations are correct, ensure that the user entries have the correct
case.
Directory server, user entries are not case-sensitive when you access exports.
When you access CIFS exports, ensure that you use the domain name and user
name, separated by a backslash (\), for example, w2k3dom01\test1.
nslookup command; this non-disruptive command requires "root" access and
your domain name. .
Information similar to the following example is displayed:
# nslookup yourdomainname
Server: 9.11.136.116
Address: 9.11.136.116#53
Non-authoritative answer:
Name: yourdomainname
Address: 129.42.16.103
Name: yourdomainname
Address: 129.42.17.103
Name: yourdomainname
Address: 129.42.18.103
The nslookup command returns the IP addresses (129.42.18.103 in the example
above) that are configured on the DNS server for Storwize V7000 Unified.
Ideally, these IP addresses should be the same as the addresses that are
configured on the Storwize V7000 Unified cluster itself. To check this, issue the
lsnw CLI command.
Address command. A successful return indicates a working connection. The
response Request timed out indicates a failed connection.
