Known issues

This section descr

ibes the known issues related to the Edge Switch 2/12, Edge Switch

2/24, and Edge Swi

tch 2/32.

Certain unauthorized devices may increase response time for fabric operations

under specific conditions with the Edge Switch 2/24

When Port Binding is enabled, unauthorized devices (devices that are not set up by

the Port Binding)witholdertechnologycantransmitnumerousfabriclogin(FLOGI)

requests, which are rejected by the Edge Switch 2/24. Processing these exchanges

may increase fabric response times for activities such as fabric builds and valid FLOGI

response time for other ports.

Workaround

Remove the una

uthorized device, change the Port Binding WWN (if this device

should be authorized), or alternatively, disable Port Binding.

HSG80 transp

arent mode not supported with IBM AIX

Use of an HSG80 with IBM AIX is restricted to operating the HSG80 in Mu ltibus mode

with the Edge Switch 2 /1 2, Edge Switch 2/ 24, and Edge Switch 2/32. Transparent

mode is not supported at this time.

Workaround

None.

HSG80 transparent mode not recommended with controller in SCSI-3 mode

with HP-UX operating systems

Due to an issue with nonexistent duplicate LUNs being displayed with the HP-UX

operating systems, the HSG80 controller is restricted to SCSI-2 mode of operation

when set to Transparent failover mode.

SCSI-3 mode of operation in M ultibus failover mode is fully supported with the use of

Secure Path software, 3.0 or later versions.

Workaround

None.
