If you are using MPIO, and it has not been configured for these devices:
1. Issue the cfgadm command.
# cfgadm –al –o show_FCP_dev
Output:
c3 fc-private connected unconfigured unknown
c3::210000e08b0a5b65 unknown connected unconfigured unknown
c3::500060e802eb2b0b,0 disk connected unconfigured unknown
c4 fc-private connected unconfigured unknown
c4::210100e08b2a5b65 unknown connected unconfigured unknown
c4::500060e802eb2b14,0 disk connected unconfigured unknown
2. Run the cfgadm command for each EVA port on the storage array.
Example:
# cfgadm –c configure c3::500060e802eb2b0b
# cfgadm –c configure c4::500060e802eb2b14
NOTE: The controller instance (c#) may differ between systems.
3. Take one of the following actions:
If you are using Solaris 9:
a. Update the sd driver:
#update_drv –f sd
b. Issue the devfsadm command to build the appropriate device files:
#devfsadm –C
If you are using Solaris 2.6, 7, or 8, reboot the host to finish configuring the new devices:
# reboot – –r
You can now view the drives using the format command. For more information, see the current
version of the multipath driver documentation, located at http://www.sun.com/storage/san.
• If you are using a volume manager application, import the volume groups. See your volume
manager documentation.
• You may need to issue the fsck command to repair any devices that were dismounted
improperly.
