Hello,
I'm trying to get san_disc from IBM Developerworks on SLES9 (kernel
2.6.5-7.282-s390x) working
(http://www-128.ibm.com/developerworks/linux/linux390/useful_add-ons_hba
api.html).
Currently I'm using version 1.4 and am not able to list the configured
target devices with PORT_LIST, other commands like HBA_LIST and RNID are
working fine.
Host adapters on z990 and target tape devices (Sun/StorageTek 9804C and
T10000A) are both connected to a McData fabric.
# export LIB_ZFCP_HBAAPI_LOG_LEVEL=1
# san_disc -c PORT_LIST -a 28 -V
(vlib.c:100)_initvlib: libzfcphbaapi.so loaded at Sep 04 14:46:04
No. Port WWN Node WWN DID Type AssociatedType
(vlib_aux.c:798)vlibErrnoToHBAStatus: ERROR: ZH_IOC_SEND_CT failed:
Input/output error
san_disc: HBA_SendCTPassThru failed
And *sometimes* I get *one* out of 19 configured targets on each of two
host adapters.
# san_disc -c PORT_LIST -a 28 -V

Message "libfcphbaapi.so loaded" is missleading since this library is
staticaly linked to san_disc.
Has anybody success with san_disc -c PORT_LIST, does it work as expected
in your environment, any ideas how I could find out what's going on here
?
Thank you !
BTW, we are using TSM with Sun/StorageTek 9840C and T10000A drives on
zLinux and TSM SAN DISCOVERY is not available on this platform.
