I'm working with SPARC Enterprise Server M4000 and the SAS HBA
SG-XPCIE8SAS-E with an attached SAS-JBOD-Unit. After poweron the server, I
changed within OBP to the HBAs Fcode.

{0} ok select /[EMAIL PROTECTED],600000/[EMAIL PROTECTED]/[EMAIL

On the SAS HBA the following command is available to show the
relation of SAS-Address to Solaris Target Number.
{0} ok show-persistent
SAS-Address Target-Nr (used by Solaris)

The problem is now if I want to change a Disk online, a new Target-ID was
created because of the different SAS-Addr. from the new disk.
It seems that this behavior is because of a fixed binding mode inside the HBA.
Q1: Is it possible to configure another binding, e.g. the PhyNum <-> Solaris
Target
Q2: Is it possible to configure the binding from Solaris
Q3: Is there a description available for the Fcode commands
Q4: What is the procedure to change a SAS-Disk online,
cfgadm -c unconfigure <AP_ID> or cfgadm -x replace_device <AP_ID>.
BTW, cfgadm -x replace_device returns
cfgadm: Hardware-specific Error: Replacement failed: I/O-Error
Thanks for your help.
