thanks whats being presented as reported by /proc/scsi/scsi seems to match the keys in /etc/multipath.conf : [root@illuminati scsi]# cat scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: HP Model: Ultrium 3-SCSI Rev: M23Z Type: Sequential-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: HP Model: HSV200 Rev: 6220 Type: RAID ANSI SCSI revision: 05 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: HP Model: HSV200 Rev: 6220 Type: RAID ANSI SCSI revision: 05 . . .

Thanks for the suggestion about setting the defaults - I'll check with product vendor. (Re the trailing whitespace after the product name - so some devices present with a trailing whitespace in the name ?) Still curious about why the defaults are being used. cheers Alan McCulloch -----Original Message----- From: centos-bounces@xxxxxxxxxx [mailto:centos-bounces@xxxxxxxxxx] On Behalf Of nate Sent: Thursday, 17 September 2009 1:08 p.m. To: centos@xxxxxxxxxx Subject: Re: multipath using defaults rather than multipath.conf contents for some devices (?) - why ?

Perhaps your config doesn't match what the system is being presented. For my MPIO my vendor suggested setting the defaults manually in the config file so my config file is: defaults { udev_dir /dev polling_interval 10 default_selector "round-robin 0" default_path_grouping_policy multibus default_getuid_callout "/sbin/scsi_id -g -u -s /block/%n" default_prio_callout /bin/true rr_wmin_io 100 rr_weight priorities failback immediate } blacklist { wwid 26353900f02796769 devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*" devnode "^hd[a-z][0-9]*" devnode "^cciss*" } devices { device { vendor "3PARdata" product "VV " path_grouping_policy multibus path_checker tur no_path_retry 60 } } multipath -l 350002ac0006a0714dm-1 3PARdata,VV [size=1.0T][features=0][hwhandler=0] \_ round-robin 0 [prio=0][active] \_ 1:0:0:3 sdc 8:32 [active][undef] \_ 1:0:1:3 sde 8:64 [active][undef] \_ 2:0:0:3 sdg 8:96 [active][undef] \_ 2:0:1:3 sdi 8:128 [active][undef] 350002ac000790714dm-0 3PARdata,VV [size=2.0T][features=0][hwhandler=0] \_ round-robin 0 [prio=0][active] \_ 1:0:0:2 sdb 8:16 [active][undef] \_ 1:0:1:2 sdd 8:48 [active][undef] \_ 2:0:0:2 sdf 8:80 [active][undef] \_ 2:0:1:2 sdh 8:112 [active][undef] /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 32 Lun: 00 Vendor: DP Model: BACKPLANE Rev: 1.05 Type: Enclosure ANSI SCSI revision: 05 Host: scsi0 Channel: 02 Id: 00 Lun: 00 Vendor: DELL Model: PERC 6/i Rev: 1.11 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 02 Vendor: 3PARdata Model: VV Rev: 0000 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 03 Vendor: 3PARdata Model: VV Rev: 0000 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 01 Lun: 02 Vendor: 3PARdata Model: VV Rev: 0000 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 01 Lun: 03 Vendor: 3PARdata Model: VV Rev: 0000 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi2 Channel: 00 Id: 00 Lun: 02 Vendor: 3PARdata Model: VV Rev: 0000 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi2 Channel: 00 Id: 00 Lun: 03 Vendor: 3PARdata Model: VV Rev: 0000 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi2 Channel: 00 Id: 01 Lun: 02 Vendor: 3PARdata Model: VV Rev: 0000 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi2 Channel: 00 Id: 01 Lun: 03 Vendor: 3PARdata Model: VV Rev: 0000 Type: Direct-Access ANSI SCSI revision: 05 nate _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos ======================================================================= Attention: The information contained in this message and/or attachments from AgResearch Limited is intended only for the persons or entities to which it is addressed and may contain confidential and/or privileged material.
