Symptoms

On Solaris[TM] 10 Operating System, an attempt to DR detach an IO Board containing the dman interface fails w/ the error "Device busy: dr@0:IOXX::pci2" where IO<##> = the number of the board targeted for removal.

Examples:
(from domain)

# cfgadm -c unconfigure IO16
May 5 14:50:50 domain-h dr: WARNING: Device busy: dr@0:IO16::pci2
cfgadm: Hardware specific failure: unconfigure IO16: Device busy: dr@0:IO16::pci2

(from SC)

sc0:sms-svc> rcfgadm -d b -c unconfigure IO16
rcfgadm: Hardware specific failure: unconfigure IO16: Device busy: dr@0:IO16::pci2

Cause

This occurs when someone tries to remove the board containing the dman interface for the domain.

Solution

Resolution
Solaris[TM] 10 DR detach of IO Board containing the dman interface fails with "Device busy: dr@0:IO<##>::pci2"

Install Patch ID: 118833-36

Relief/Workaround

    # ndd -set /dev/dman man_set_active_path '0 0 '

where = [0,1,2,3...]. In the case of this example, one would use:

    # ndd -set /dev/dman man_set_active_path '0 0 0'

to configure the dman interface to use eri0 on IO7.

Internal Comments
For the internal use of Sun Employee's.

This is a result of Bug ID: 6266573.
This occurs when one tries to remove the board containing the dman interface
for the domain. Use the following ndd command on the domain to determine
the location of the dman interface:
# ndd /dev/dman man_pathgroups_report

@
MAN Pathgroup report: (* == failed)
===============================================================================
Interface Destination Active Path Alternate Paths
-------------------------------------------------------------------------------
dman0 Master SSC eri2 eri0 exp 7, eri2 exp 16

@
As one can see in this example, dman0 is currently using eri2 which is located
on IO16, the board targeted for removal.Solaris is supposed to automatically
configure the dman interface to use an eri interface on another board and
complete the operation. This new bug is a regression from previous Solaris
versions and only affects Solaris 10.

**This bug has been fixed in Patch ID: 118822-04.**
