HP 8/20q HP StorageWorks H-series SN6000 Fibre Channel Switch Release Notes (5 - Page 8

• 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 booting a server running SUSE 9 with Emulex-based HBA, and using TR connections with storage on a remote fabric, the storage might not be completely discovered by the server. This occurs when the I/O scan completes before the server has logged into the storage. To correct this condition, ensure that HP fibreutils are installed, and use the hp_rescan -a command to rescan all of the adapters in the system. • When connecting an HP StorageWorks 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. • HBA Connection may not recover after switch port goes offline. Connection may not recover after a switch port is set offline and back online when connected to an HP StorageWorks 81E PCle FC HBA (LPe12000 HBA) or HP StorageWorks 82E PCle FC HBA (LPe12002 HBA) for hosts running VMware 3.5.0. This issue is corrected with Emulex driver version elx_7.4.0.39 or later, available on the Emulex website and on the VMware website. • HBA may not discover storage target on remote fabric. An Emulex-based HBA running on SUSE 9 does not always find targets on remote fabrics after booting the server. This issue is corrected with Emulex driver version 8.0.16.40_p2 or later. The affected HBAs include: • HP StorageWorks 81E PCle FC HBA • HP StorageWorks 82E PCle FC HBA • HP StorageWorks FC2143 • HP StorageWorks FC2243 • HP StorageWorks FC2142SR • HP StorageWorks FC2242SR • HP 4Gb HBA for HP c-Class BladeSystem • HP Emulex-based BL20p Fibre Channel Mezz HBA • HP Emulex-based BL25/30/35/45p Fibre Channel Mezz HBA • 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) 8
