2. Confirm you have assigned the created virtual tapes to the desired virtual devices
from the Web Control Panel: “Tools” > “Assign virtual tapes...”.
3. Capture a Debug Log from “Browser Links”, and then contact Cybernetics Technical
Support (See “Browser links” on page 70 )
Problem : The Web Control Panel appears as a blank gray box. (The Java applet failed to
load.)
Solution :
1. Clear the Web browser cache.
2. Download and install the latest version of the Java™ web browser plug-in from the
Sun Microsystems Java website at http://www.java.com .
Problem : The Web Control Panel displays a “Lost communication” box, saying “The unit
is not responding.”
Solution :Telnet to the miSAN-V-Series, and then login as
menu
. If the “Offline Mainte-
nance” menu appears, try exiting the menu to bring the miSAN-V-Series back online,
which effectively restarts the unit. While restarting the miSAN-V-Series, read the startup
messages, and if the unit goes back to the “Offline Maintenance” menu, act accordingly to
fix the problem: for a SCSI bus problem, inspect the SCSI bus cabling. Else, if the prob-
lem persists, contact Technical Support for assistance (See
Appendix E, “ Technical Sup-
port” ).
Problem : One of the internal disk drives seems to have gone bad.
Solution :Log in to the 3ware Disk Manager 2 to see the status of the drive (See “Drive
Information Page” on page 122 ). If the disk drive is bad, follow instructions for removing
the drive in “Removing a Drive” on page 138 and then instructions for adding a drive in
“Adding a Drive” on page 138 . A good way to test the disk drive once it is removed from
the miSAN-V-Series is to install it in a PC and run a low-level (long) format. If the format
completes successfully, then the problem may be elsewhere. If the format fails, as
explained in
“Product Warranty Statement” on page vi , contact Cybernetics Technical
Support (See Appendix E, “ Technical Support” ) to initiate a service request. Customers
can opt to send the hard drive to Cybernetics to coordinate the service request through
the manufacturer or obtain service directly from the manufacturer.
Problem : The speeds on the miSAN-V-Series are slower than expected.
Solution :There are several possible causes for slower than expected speeds. Some of
the most common:
1. Slower than expected speeds to the miSAN-V-Series (i.e., writing/reading virtual
tapes)
a. Network Attached
• Make sure that ALL the networking hardware is capable of and connecting at
1000Base-T (1000 megabits per second).
Note :If the data travels through a single medium that is slower than 1000Base-T (e.g.,
100Base-T),then the data will travel at the slower speed throughout all the network.
• Make the data path as simple as possible, such that the number of network
hops is reduced if possible. Implement a dedicated 1000Base-T SAN
(subnetwork) for the miSAN-V-Series and connected data sources.
