Re: RHEL 4 LUNS not visible on one PATH
If so, do you see the controller listed in the events output? Do you have activity/status lights?
It would help verify that it's really there as far as the OS and hardware are concerned.

Re: RHEL 4 LUNS not visible on one PATH
If that is the case then I would expect to see what you are seeing. The qlogic driver 'hides' all but one path for each Lun from the SCSI subsystem , so you only see one path.
I can check the parameter names when I get to work (posting this from mobile).

Re: RHEL 4 LUNS not visible on one PATH
If failover is enabled, then you can then use the SANSurfer tool to enumerate the individual paths.

Re: RHEL 4 LUNS not visible on one PATH
Nail on the head! I see the cat /sys/module/qla2xxx/ql2xfailover set to 1, but the modprobe.conf file does not have failover to 1. Here it is from modprobe.conf
grep -i qla /etc/modprobe.conf
alias scsi_hostadapter1 qla2xxx_conf
alias scsi_hostadapter2 qla2400
options qla2xxx ql2xmaxqdepth=2
install qla2xxx /sbin/modprobe qla2xxx_conf; /sbin/modprobe --ignore-install qlx
remove qla2xxx /sbin/modprobe -r --first-time --ignore-remove qla2xxx && { /sbi}
options qla2xxx extended_error_logging=1
options qla2xxx ql2xfailover=0
so how could the /sys/module/qla2xxx/ql2xfailover be set to 1? Please clarify ASAP. Thanks for all the support.
Thanks
Brian
