I would kindly ask someone if you could check my multipath.conf file, I have used this file for my SLES10SP3 Server with FCP attached LUNs, NetApp Metrocluster. But after takeover and giveback the filesystems created on these LUNs become read-only.

The part after device is looking like this

vendor "NETAPP"
product "LUN"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout "/sbin/mpath_prio_alua /dev/%n"
prio "alua"
features "1 queue_if_no_path"
hardware_handler "0"
path_grouping_policy group_by_prio
failback immediate
rr_weight uniform
rr_min_io 128
path_checker tur

Thank you in advance for your tips and contributions.
