<p>If you are experiencing one of the problems listed below, you may begin
troubleshooting by performing the actions listed. This is not a comprehensive
list, so some problems may require actions beyond those listed here. To find
information that may help you troubleshoot problems, see <a href="rzahqmsgpi.htm#rzahqmsgpi">Check message and job logs</a>.</p>
<p><span class="bold">Initializing the service processor configuration fails</span></p>
<p>If there is a message CPDC4xx or CPFC4xx in the system operator's
message queue (QSYSOPR) or the job log of the batch job or interactive user
involved, see <a href="rzahqibmdirectortroub.htm#rzahqibmdirectortroub">IBM Director Troubleshooting</a>.</p>
<p><span class="bold">When installing or starting a server, the NWSD status
stays VARIED OFF</span></p>
<ul>
<li>Ensure that all required network server host adapters configured for the
server are varied on before installing or starting a server. If a network
server host adapter will not vary on, check for messages in the network server
host device's message queue.</li>
<li>If there is a message CPDC4xx or CPFC4xx in the system operator's
message queue (QSYSOPR) or the job log of the batch job or interactive user
involved, see <a href="rzahqibmdirectortroub.htm#rzahqibmdirectortroub">IBM Director Troubleshooting</a>.</li></ul>
<p><span class="bold">With the hosted system powered on, a server will not start</span></p>
<p>See <a href="rzahqproblemssharing.htm#rzahqproblemssharing">Problems sharing hosted system hardware</a>.</p>
<p><span class="bold">The hosted system's console displays 'No iSCSI devices
found' or prompts for diskette</span></p>
<ul>
<li>The iSCSI HBA configured for boot in the hosted system was unable to do
so.</li>
<li>There may be an iSCSI configuration problem. See <a href="http://www.ibm.com/servers/eserver/iseries/integratedxseries/iscsireadme/troubleshooting.html" target="_blank">iSCSI Troubleshooting </a>
<img src="www.gif" alt="Link outside the Information Center." />
<br />(www.ibm.com/servers/eserver/iseries/integratedxseries/iscsireadme/troubleshooting.html).</li>
<li>If message CPPC056 is in the Product Activity Log, a CHAP configuration
problem is likely.</li>
<li>There may be a network problem between the hosted system's iSCSI
HBA configured for boot and the iSeries&trade; HBA corresponding to the path configured
for the NWSD's system drive storage space. See <a href="rzahqbootandstoragepathanal.htm#rzahqbootandstoragepathanal">Boot and storage path network analysis</a>.</li></ul>
<p><span class="bold">The NWSD status is VARIED ON, but Windows does not begin
to boot</span></p>

<li>If message CPPC056 is in the Product Activity Log, a CHAP configuration
problem is likely.</li>
<li>There may be a network problem between the hosted system's iSCSI
HBA configured for boot and the iSeries HBA corresponding to the path configured
for the NWSD's system drive storage space. See <a href="rzahqbootandstoragepathanal.htm#rzahqbootandstoragepathanal">Boot and storage path network analysis</a>.</li></ul>
<p><span class="bold">The NWSD status is DEGRADED</span></p>
<p>Ensure that all required network server host adapters configured for the
server are varied on. If a network server host adapter will not vary on,
check for messages in the network server host device's message queue.</p>
<p><span class="bold">Storage using a path other than the boot path does not
show up in Windows</span></p>
<ul>
<li>There may be a network problem between the hosted system and the iSCSI
HBA in the iSeries that corresponds to the non-boot path. See <a href="rzahqbootandstoragepathanal.htm#rzahqbootandstoragepathanal">Boot and storage path network analysis</a>.</li>
<li>If message CPPC056 is in the Product Activity Log, there is a CHAP problem.
In this case, it is most likely due to a problem with the digital certificates
that the Windows environment on iSeries needs to securely transfer its own
sensitive data between i5/OS and Windows. See <a href="rzahqmanagingpathcertificates.htm#rzahqmanagingpathcertificates">Managing path certificates</a>.</li></ul>
<p><span class="bold">Storage using a path other than the boot path sometimes
shows up late in Windows</span></p>
<ul>
<li>This is normal the first time the server is started after you change certain
i5/OS configuration information, such as SCSI local interface information
in the network server host adapter or CHAP information in the remote system
configuration.</li>
<li>This is normal if an iSCSI HBA in the hosted system has not been used
with this particular NWSD before. This would be the case when an iSCSI HBA
is replaced in the hosted system, or when using a different hosted system
as a hot spare.</li>
<li>If your application involves an automatic start service that is sensitive
to the above situations, see the <a href="http://www.ibm.com/servers/eserver/iseries/integratedxseries/iscsireadme/advancedtasks.html">Advanced
iSCSI tasks </a>
<img src="www.gif" alt="Link outside the Information Center." /> web page (www.ibm.com/servers/eserver/iseries/integratedxseries/iscsireadme/advancedtasks.html).</li></ul>
<p><span class="bold">User enrollment or submit remote command fails with NTA02BB,
NTA028A, NTA028B</span></p>
<ul>
<li>There is a problem with the digital certificates that the Windows environment
on iSeries needs to securely transfer its own sensitive data between i5/OS
and Windows. See <a href="rzahqmanagingpathcertificates.htm#rzahqmanagingpathcertificates">Managing path certificates</a>.</li>
<li>For NTA028A and NTA028B, ensure that the time and date on the hosted system
doesn't differ significantly from the date on the iSeries, as this can
cause digital certificates to appear to be invalid.</li></ul><img src="deltaend.gif" alt="End of change" />
