Hi!
I have StorageTek 2530 storage, which has two controllers. On host side
I have LSI LOGIC two SAS port cards. I've connected one cable from
LSI port1 to StorageTek ControllerA, and second SAS cable from LSI
port2 to StorageTek ControllerB.
On storage, I've set up initiators type to Linux.
But, I just can't get multipath working. For example:
# multipath -ll
sdc: checker msg is "readsector0 checker reports path is down"
sde: checker msg is "readsector0 checker reports path is down"
sdg: checker msg is "readsector0 checker reports path is down"
sas-mysql (3600a0b80003abc5c00000b654a916617) dm-1 SUN,LCSM100_S
[size=115G][features=0][hwhandler=0][rw]
\_ round-robin 0 [prio=0][active]
\_ 1:0:0:1 sdc 8:32 [failed][faulty]
\_ 1:0:1:1 sdf 8:80 [active][ready]
sas-xen (3600a0b80002fcd18000014544a9166fb) dm-2 SUN,LCSM100_S
[size=21G][features=0][hwhandler=0][rw]
\_ round-robin 0 [prio=0][active]
\_ 1:0:0:2 sdd 8:48 [active][ready]
\_ 1:0:1:2 sdg 8:96 [failed][faulty]
quorum (3600a0b80002fcd18000014514a9165b4) dm-0 SUN,LCSM100_S
[size=100M][features=0][hwhandler=0][rw]
\_ round-robin 0 [prio=0][active]
\_ 1:0:0:0 sdb 8:16 [active][ready]
\_ 1:0:1:0 sde 8:64 [failed][faulty]
So, all paths on my second controller are failed/faulty....
Here is my multipath.conf:
defaults {
udev_dir /dev
polling_interval 10
selector "round-robin 0"
path_grouping_policy multibus
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout /bin/true
path_checker readsector0
rr_min_io 100
max_fds 8192
rr_weight priorities
failback immediate
no_path_retry fail
user_friendly_names yes
}
blacklist {
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
devnode "^hd[a-z]"
}
multipaths {
multipath {
wwid
3600a0b80002fcd18000014544a9166fb
alias sas-xen
path_grouping_policy group_by_prio
path_checker tur
prio_callout "/sbin/mpath_prio_tpc.static /dev/%n"
}
multipath {
wwid
3600a0b80003abc5c00000b654a916617
alias sas-mysql
path_grouping_policy group_by_prio
path_checker tur
prio_callout "/sbin/mpath_prio_tpc.static /dev/%n"
}
multipath {
wwid
3600a0b80002fcd18000014514a9165b4
alias quorum
path_grouping_policy group_by_prio
path_checker tur
prio_callout "/sbin/mpath_prio_tpc.static /dev/%n"
}
}
I've also tried:
multipath {
wwid
alias
path_grouping_policy failover
path_checker readsector0
path_selector "round-robin 0"
failback immediate
no_path_retry queue
}
for those 3 wwid's...
I'm kinda lost... I've found this, but it is for FC storage, and mine
is SAS type...

Thank you...
