Also noticed cfgadm shows the second device controller c3 shows connected to ESI type instead of disk type like for c2. c3 wwn matches fc1's wwn number. so I guess if I moved the fiber to fc4 on the 3510's controller board it will start showing second path. # cfgadm -al Ap_Id Type Receptacle Occupant Condition c0 scsi-bus connected configured unknown c0::dsk/c0t0d0 CD-ROM connected configured unknown c1 scsi-bus connected configured unknown c1::dsk/c1t0d0 disk connected configured unknown c1::dsk/c1t1d0 disk connected configured unknown c1::dsk/c1t2d0 disk connected configured unknown c1::dsk/c1t3d0 disk connected configured unknown c2 fc-private connected configured unknown c2::216000c0ff8a758b disk connected configured unknown c3 fc-private connected configured unknown c3::226000c0ffaa758b ESI connected configured unknown usb0/1 unknown empty unconfigured ok usb0/2 unknown empty unconfigured ok usb1/1.1 unknown empty unconfigured ok usb1/1.2 unknown empty unconfigured ok usb1/1.3 unknown empty unconfigured ok usb1/1.4 unknown empty unconfigured ok usb1/2 unknown empty unconfigured ok > > so could I just move the connection from fc1 to fc4 and expect > mpathadm to see two paths to the disks ? > > will it hurt my raidz2 zpools which are already using block devices > with those long WWNs. > > I am running sol 10 u3 with zpool version 15 (patched yesterday to get > to this level) > > -- > Asif Iqbal > PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu > A: Because it messes up the order in which people normally read text. > Q: Why is top-posting such a bad thing? > -- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu A: Because it messes up the order in which people normally read text.
