58. Question: To create a dual SB9200 model HyperStack, how many license keys do I need to purchase?
Answer: Two; one for each of the two SB9200 chassis modules. Since each HyperStack License Key SKU includes two HyperStack cables, two license keys
will have the required four HyperStack cables.
59. Question: Does the HyperStack feature require the FT feature or vice versa?
Answer:
No, the HyperStack and FT features are independent, but are available only on the dual CPU SB9200 model.
60. Question: Is there a way to manually force a CPU Failover with the FT feature installed?
Answer:
Yes, there is an administrator switchover command that causes the supervisor operation on the primary CPU to be switched over to the hot standby
secondary CPU. Note: the previous primary CPU then becomes the secondary CPU and is in hot standby mode (rather than in faulted mode with an actual CPU
failover initiated by the system).
61. Question: What happens if the HyperStack cables are not configured exactly as specified in the HyperStack Cable Installation Guide?
Answer: The SB9200 firmware checks for proper HyperStack ICC cable installation and generates an alarm when the cables are not installed in the proper
configuration. The switch will boot up, but the alarm condition cannot be cleared until the cable configuration is correctly installed.
62. Question: If an SB9200 does not have either the FT or HyperStack feature, is there any reason to run the later firmware (version 6.6) and EFS2007 software
(version 6.07)?
Answer:
Yes, the inherent fault tolerance of an SB9200 dual CPU model is improved with the later firmware and software. With previous firmware (6.2) and
software (6.03) versions, the supervisor could only run on CPU 0 (in slot 0). If CPU 0 failed, the user had to physically swap the CPU blades to re-boot. With the
6.6 version firmware and the 6.07 version software, the user can immediately re-boot and run the supervisor on the surviving CPU in either slot 0 or slot 1.
63. Question: Is there a free trial period available on either the FT License or HyperStack Feature License?
Answer: Not at this time. Please contact your respective QLogic Channel or OEM Sales representative.
