HP H-series SN6000 and 8/20q Fibre Channel Switch Release Notes

Important information
This section provides important information about the H-series switches.
• When launching QuickTools, some Java versions erroneously launch a popup window
indicating a possible vulnerability. To launch QuickTools, do not select option to block
components.
• Changing the password for the images account causes firmware updates and support file
creation to fail. This account is restricted to use only by the switch for file transfers and the
switch operates with the default password for this account. HP recommends not to change the
password for the images account.
• QLogic-based CNA driver might require an update. When using Transparent Router to
supported Cisco Nexus switches and mapping to Windows servers with QLogic-based CNAs
(CN1000Q), PLOGI might not retry on server boot when ACC is rejected with Busy. This is
resolved in CNA driver version 9.1.11.12 or later.
• SAN Connection Manager Support. The SAN Connection Manager (SCM) application version
3.40 is the recommended version for the the SN6000 Fibre Channel Switch and HP 8/20q
Fibre Channel Switch. SCM can manage the 8/20q Fibre Channel Switch and the SN6000
Fibre Channel Switch with active transparent router ports (TR_Ports). However, SCM does not
manage or discover remote switches or devices in the remote fabric.
• When using QuickTools with a large fabric, Java memory errors can occur. To avoid this issue,
increase the Java heap size as follows:
1. Open the Java control panel.
2. Select the Java tab.
3. Under Java Applet Runtime Settings, click View.
4. Double-click Java Runtime Parameters, and then enter -Xmx300m in the box.
5. Click OK.
• When connecting an HP MSA2000fc, MSA2000fc G2, or P2000 G3 FC Modular Smart Array
System to an H-series switch, the switch ports are presented as hosts in the storage unit GUI.
This occurs because by default, the H-series switch executes a Device Scan, where the switch
logs into connected devices and queries them for information. The storage units then present
the switch WWN as a host. This can be avoided by disabling Device Scan on the switch port
before connecting the storage port to the switch port.
If the storage port is connected before disabling Device Scan and the switch ports are presented
as hosts, you can remove a host entry for the switch by disabling Device Scan on the switch
port and rebooting the storage controller. The status of the host changes to discovered=no,
and then it can be removed.
• Optical transceivers. Only the HP 8-Gb Short Wave FC SFP+ (part number AJ718A), HP 8-Gb
Long Wave 10 km FC SFP+ (part number AW584A), and HP 4-Gb Short Wave FC SFP (part
number A7446B) tranceivers are supported for use in the H-series switches.
Each switch Fibre Channel port is supported by a data buffer with a 16 credit capacity; that
is, 16 maximum sized frames. With the use of a long wave transceiver, this enables full
bandwidth over approximately:
◦ 3.3 kilometers at 8 Gb/s (4.8 credits/km)
◦ 6.6 kilometers at 4 Gb/s (2.4 credits/km)
◦ 10 kilometers (limited by the transceiver capability) at 2 Gb/s (1.2 credits/km)
The 8-Gb transceivers do not support 1 Gb/s port speed. If the port speed is configured as
1 Gb/s, the port is disabled and its state will be changed to Downed. To correct this, you
can configure the port to a supported speed (2 Gb/s, 4 Gb/s, 8 Gb/s, or auto-detect).
