Hello,
having a definition in multipath.conf such as this
devices {
device {
vendor "NETAPP"
product "LUN"
...
features "1 queue_if_no_path"
...
hardware_handler "1 alua"
...
}
is it possible to change it to
devices {
device {
vendor "NETAPP"
product "LUN"
...
features "0"
no_path_retry 5
hardware_handler "1 alua"
...
}
and get immediately on the fly the cnages with
multipath -v2 ?
Or are these changes that require a reboot?
If the answer is yes, can it be that a former blocked device not giving back error because of its "queue" configuration, then after the change and 5 retries now gives error to the SCSI layer?
System is RH EL 5.8 with
kernel 2.6.18-308.24.1.el5
and
device-mapper-multipath-0.4.7-48.el5_8.1
Thanks in advance,
Gianluca
