Creating multipath device with FC Disks

Hello,

I am trying to setup a storage server with salvaged equipments:
QSSC-S4R server, with QLogic 2562 FC HBA's
Clariion KTN-STL4 4GB FC Enclosures
Disks Salvaged from EMC Vmax

Disks are 520B sector size so i converted to 512B in linux environment and create multipath successfully. But in solaris, it doesnt create any multipath devices

Code:
root@replica:~# mpathadm list lu
root@replica:~# 

root@replica:~# luxadm probe

Any way to create multipath device manually?

Thanks.

Hi,

You should be able to create the multi path devices with;

Code:
# stmsboot -D fp -e

Hi,

Thanks for the reply, it seems already enabled:

Code:
root@replica:/kernel/drv# stmsboot -D fp -e
STMS is already enabled. No changes or reboots needed

Regards.

Hi,

This would indicate that the server was already connected to the SAN and that the command has been run to stop the system displaying multiple paths for each device, normally the first time you run stsmbooyt a reboot is required.

Solved with adding lines to /kernel/drv/scsi_vhci.conf

Code:
device-type-scsi-options-list =
  "HITACHI HUS15603 CLAR300", "f_sym",
  "STEC    ZIV2A210 CLAR200", "f_sym";

scsi-vhci-failover-override =
  "HITACHI HUS15603 CLAR300", "f_sym",
  "STEC    ZIV2A210 CLAR200", "f_sym";

then

Code:
stmsboot -u

now everything is work correctly
