 Chapter 10 Troubleshooting

When the OS is started, the message 
"Path Not Found" is displayed and 
accessing the SPS device fails.

Check the disk array unit is recognized by the OS.
Refer to the file "/proc/scsi/scsi" and check if "Vendor: NEC" 
and "Model: DISK ARRAY" are shown. If the disk array unit 
is not recognized, they are not shown. When they are not 
shown, check the FC cables are connected correctly.
The SPS recognizes the path information at its first startup, 
and creates and retains the information in a status setting 
file. If correct connection to the disk array unit fails to be 
configured in the first OS startup after installation of SPS, it 
can cause incorrect path information to be recorded. In this 
case, delete the setting file recorded in the SPS, and then 
restart the OS.
If the problem persists even after checking and performing 
above mentioned, please contact the Support Service.

SPS cannot be started when a 
certain RPM is updated.

Updating initscripts or iscsi-initiator-utils in a RHEL 
environment may disable the settings of automatic startup 
for SPS, and SPS may not be started automatically when 
the OS is started. 

Check /etc/rc.d/rc.sysinit to see the settings of automatic 
startup for SPS are configured. Run the following command 
and if there is no output, it indicates the settings of 
automatic startup for SPS are not configured.

# grep mkdd /etc/rc.d/rc.sysinit

If the settings of automatic startup for SPS have not been 
configured, configure them again and restart the OS. See 
the followings for setting automatic startup for SPS.

# cd /etc/rc.d

<Red Hat Enterprise Linux 5 (FC connection)>

# patch -b -p0 < 
/opt/nec/sps/patch/rc.sysinit.rhel5.diff

<Red Hat Enterprise Linux 5 (iSCSI connection)>

# patch -b -p0 < 
/opt/nec/sps/patch/iscsi.rhel5.diff

When you run the patch command but an error message is 
shown, it indicates the patch file is not applied correctly. In 
this case, add the line with "+" shown on the first row of the 
patch file to /etc/rc.d/rc.sysinit or /etc/rc.d/init.d/iscsi.
If the problem persists even after checking and performing 
above mentioned, please contact the Support Service.
