Compaq StorageWorks Fibre Channel SAN Switch 16 Release Notes 9
Known Issues
This section describes the known issues and problems related to the Fibre
Channel SAN Switches, as of 6/1/00.
Fibre Channel SAN Switch
Only eight E-ports per switch are supported.
QuickLoop
QuickLoop, with large numbers of looplets (16), can cause some adapters to
time out during initialization, resulting in repetitive initializations. A new
Telnet command has been added that can speed up initialization:
qlUnmaskLipa [ 0 | 1 ]
The parameter can be set to “0” or “1”. When set to “0”, initializing a looplet
is off. When set to “1” (the default for new switches), initializing a looplet is
on. When the parameter is set to initializing a looplet, the v2.1.7 QuickLoop
masks the Arbitrated Loop Physical Address (AL_PA) bits in the Loop
Initialization Procedure (LIPA) frame using the LIPA bitmaps of those
looplets that stay online. Setting this option on disables the LIPA bitmap
masking and opens AL_PAs for taking by devices in the looplet being
initialized in the LIPA phase, thus allowing the Primary to claim the same
AL_PA in the case of fail-back in Compaq's HA environment.
Make sure that this parameter is set to “1.”
