Hi Guys,
We have RHEL 5.9 and NetApp 7 mode storage. I have problem in creating partition in those NetApp LUNs It is not allowing me to create partition. We tried a lot of things, but didn't help. Currently we investigate multipath.conf file and lvm.conf file.
Does anyone have any idea what's wrong?
My multipath.conf file
defaults {
user_friendly_names no
queue_without_daemon no
flush_on_last_del yes
max_fds max
pg_prio_calc avg
}
blacklist {
devnode "^hd[a-z]"
devnode "^(ram|raw|loop|fd|md|dm-|sr|sdc|st)[0-9]*"
devnode "^cciss.*"
}
devices {
device {
vendor "NETAPP"
product "LUN"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout "/sbin/mpath_prio_alua /dev/%n"
features "3 queue_if_no_path pg_init_retries 50"
hardware_handler "1 alua"
path_grouping_policy group_by_prio
failback immediate
rr_weight uniform
rr_min_io 128
path_checker tur
path_selector "round-robin 0"
flish_on_last_del yes
}
}
My lvm,conf file
preferred_names = [ "^/dev/cciss/", "^/dev/mpath", ]
filter = [ "a/sda[1-9]$/" "a/mpath.*/" "r/.*/" ]
And I have attached the error that which i got while creating partition, Thanks in advance by Magesh
