| Hello all,
we are running an IBM p690 with AIX 5.2 ML 06 and I have attached an SGI
TP9500 to its two Emulex HBAs (6239). The TP9500 is an Engenio 5884 based
array similar to IBM's FAStT900 (as I understand it). Initially, the AIX
system would only see the exported LUNs as "FC Disk Other", without any
native fail-over.
I then did add the following file to AIX's ODM by
% odmadd objet-tp9500_ibm-dac
% cat objet-tp9500_ibm-dac
PdAt:
uniquetype = "array/fcp/ibm-dac"
attribute = "model_name"
deflt = "TP9500 "
values = ""
width = ""
type = "R"
generic = ""
rep = "s"
nls_index = 0
and then I did a
% cfgmgr -v fcs0
% cfgmgr -v fcs1
which generated dac0, 1, 2, 3 devices but no dar ones.
I then did a
% cfgmgr -v
which indeed generated dar0 and dar1 but now the newly discovered LUNs appear
as 'Defined' and not 'Available':
hdisk16 Available 2v-08-01 Other FC SCSI Disk Drive
hdisk17 Defined 2v-08-01 fcparray Disk Array Device
hdisk18 Available 3e-08-01 Other FC SCSI Disk Drive
hdisk19 Defined 2v-08-01 fcparray Disk Array Device
hdisk20 Available 2v-08-01 Other FC SCSI Disk Drive
hdisk21 Available 3e-08-01 Other FC SCSI Disk Drive
hdisk22 Defined 3e-08-01 fcparray Disk Array Device
hdisk23 Defined 3e-08-01 fcparray Disk Array Device
Note that hdisk16, 18, 20 and 21 are LUNs that are in use in 2 volume
groups since some time ago.
Looking at the output of the 'cfgmgr -v' command for hdisk17, 19, 22 and 23, I
noticed:
================================== >>>

================================== >>>
What is going wrong here? Is anything else needed to be added to the ODM of
the AIX system? Any idea or hint of the problem would be greatly appreciated!
