During error monitoring, when a failure is detected on the monitored array unit, you can start an Email Report or one specified application. Complete the following instructions to start a report.
In Error Alert Mode, click the Email Error Report Enabled check box and the Execute Application check box to enable them.
On the Tool menu, select Error Monitoring Options., or select Error Monitoring -> Options in the tool bar. See the Error Monitoring help page for more information and instructions to set up error monitoring.
Check the status of array unit components: drives, controllers, batteries, fans, power supply and cache. A status check is done on an array unit for which the of the Error Alert Flag in ”Error Monitoring Options” is selected.
In the Array Properties window, select Refresh
The status of an array unit for which error monitoring is specified is checked. When checking begins, the icon of an array unit is displayed with the check result reflected by the icon.
The status check performs functions equivalent to those of error monitoring. When an error is detected in an array unit that has been checked, output of a log, sending of an Email, and restarting of a specified application are performed in accordance with the settings of the monitor options.
See the host installation guides if the array cannot see the host after LUNs have been created and the LUNs have been mapped to the iSCSI targets. Host OS guides point to the iSCSI initiator application that runs on the host and maps the host to the array.
Users are responsible for operation and normal maintenance of the computer(s) that host Navigator 2 software. The following are guidelines for troubleshooting Navigator 2 software operations:
Check the cabling and the LAN. Verify that both the computer and LAN cabling are firmly attached, and that the LAN is operating properly.
Reboot the computer. Close any programs that are not responding. If necessary, reboot the computer.
If Navigator 2 does not succeed in connecting to the array unit, the following message may display:
An invalid response was received from the subsystem
This indicates that Navigator 2 may have been connected to the array unit while the array unit automatically rebooted. Connect to the array unit again after approximately three minutes.
Navigator 2 may hang up in the following cases:
The communication with the connected array unit fails due to controller blockage, array unit failure, or disconnected LAN connection, etc., or the array unit receives a Reset/LIP from the host.
Other applications are working concurrently and memory utilization or a CPU use rate is high.
If Navigator 2 hangs, terminate it forcibly and check the array unit status and the connection status of the LAN. Reboot Navigator 2 again.
