Chapter 12. Host configuration 555
Checking zoning
On the IBM Flex System FC3171 8Gb SAN Switch. the zoning is checked as shown in
Figure 12-65. Here, the WWN is defined in zone with IBM Flex System V7000 Storage Node
canisters.
Figure 12-65 Check WWN is defined in zone
Again, this check should be repeated on the second IBM Flex System FC3171 8Gb SAN
Switch for the second HBA fcs1.
Checking host definition on IBM Flex System V7000 Storage Node
From the administration access of IBM Flex System V7000 Storage Node, Figure 12-66
shows that both HBAs WWNs are correctly displayed in a defined host.

12.5.4 Installing the 2145 host attachment support package
To correctly configure multipathing of IBM Flex System V7000 Storage Node volumes to an
AIX compute node requires the proper device type of 2145, which should be displayed when
querying with AIX (lsdev -Cc disk command later). The 2145 host attachment support fileset
is required prior to running cfgmgr, which searches for new devices. Running cfgmgr prior to
installing the host attachment support fileset will result in the LUNs being configured as
“Other SCSI Disk Drives” and will not be recognized by SDDPCM.
