Troubleshooting: Your Storage Array Software

22 Determine if there is an excessive amount of network traffic to one or 

more RAID controller modules. 
This problem is self-correcting because the EMW software periodically 

retries to establish communication with the RAID controller modules in 

the storage array. If the storage array was unresponsive and a subsequent 

try to connect to the storage array succeeds, the storage array becomes 

responsive.
For an out-of-band managed storage array, determine if management 

operations are taking place on the storage array from other storage 

management stations. A RAID controller module-determined limit exists 

to the number of Transmission Control Protocol/Internet Protocol 

(TCP/IP) connections that can be made to the RAID controller module 

before it stops responding to subsequent connection attempts. The type of 

management operations being performed and the number of management 

sessions taking place together determine the number of TCP/IP 

connections made to a RAID controller module. This problem is self-

correcting because, after some TCP/IP connections terminate, the RAID 

controller module then becomes responsive to other connection attempts.

23 If the storage array is still unresponsive, a problem might exists with the 

RAID controller modules. Contact your Technical Support representative.

You can use the Locate Physical Disk option to physically locate and identify 

one or more of the physical disks in an expansion enclosure by activating 

physical disk LEDs. 
To locate the physical disk:

1 Select the Physical tab.
2 Select the physical disks that you want to locate.
3 Select Physical Disk Blink Physical Disk.

The LEDs on the selected physical disks blink.
