Real-time server error: Selected component is not connected
to the XP Disk Array or no activity happening on the component
If the following error appears on the RealTimeChart screen - The selected component may no
longer be connected to the array or does not have any activity happening
currently. Please verify if the selected component is currently active.
If you see that the selected component is currently active, then please
try recreating the device files as the device file may not be accessible
by RealTimeServer, do the following:
1. Verify if the selected component (LDEV or RAID group) is active. For example, you can verify the
status of the LDEV or RAID group on the Array view LDEV screen under the LDEVIO and LDEV MB
columns, where the I/Os and M/Bs happening on the selected LDEV or the LDEV associated with
the selected RAID group are displayed.
2. If the selected LDEV or RAID group is active and the above error persists, recreate the device file
in your host agent. Following are the steps to recreate the device file:
a. Login to the host agent as root
b. Recreate the SCSI device special files using the command - # /dev/MAKEDEV sg
Unable to browse to the management station
To identify the management station to the DNS server:
1. Add <IP Address> to the list of addresses to bypass your proxy server.
NOTE:
Using Internet Explorer as an example, follow this procedure to add your IP address:
a. Go to Tools > Internet Options> Connections > LAN settings > Advanced
b. In the Exceptions text box, place your cursor at the end of the domain list
c. Enter a semicolon and your IP address, including the asterisk if you want to include everything
within the last octet
d. Click OK
2. Close and then re-open the web browser
3. Enter http://<IP Address>/pa or https://<IP Address>/pa
4. Enter administrator for the username and administrator for the password (unless you have changed
it from the default) and save, if desired
5. If the browser returns with an unresolved hostname for http://[servername].[domain name]/pa
or https://[servername].[domain name]/pa, change it to http://<IP Address>/pa or https://<IP
Address>/pa; this takes you to the management station's default XP Perf Advisor page.
