16.Turn on the host system.
1.4.5 Verifying the ESS configuration
To verify the configuration of the ESS on the AIX host system, type the following
command:
lsdev -Cc disk | grep 2105
A list of all IBM ESS devices is displayed as shown in the following example:
hdisk3 Available 30-68-01 IBM FC2105F20
hdisk4 Available 30-68-01 IBM FC2105F20
hdisk5 Available 30-68-01 IBM FC2105F20
These indicate that the installation is successful.
If a device is listed as another type of device, the message shown below is
displayed. This message indicates that the configuration was not successful.
hdisk3 Available 30-68-01, Other FCSCSI disk device
hdisk4 Available 30-68-01, Other FCSCSI disk device
hdisk5 Available 30-68-01, Other FCSCSI disk device
1.4.6 ESS devices with multiple paths per LUN
The ESS supports multiple path configurations for a LUN. This means that you
can have multiple hdisks available on the AIX server for each physical LUN. If
you create a PVID sector 0 of a LUN and you delete all hdisks from the system
with the rmdev command, you must restart the system. If you want to restore all
multiple paths for all LUNS, use the cfgmgr command for each Fibre Channel
adapter.
1.5 IBM eServer xSeries or IBM NUMA-Q FC attachment
This topic tells you how to attach an ESS to an xSeries or an IBM NUMA-Q host
system with Fibre Channel adapters. We also tell you how to install and configure
the IOC-0210-54 adapter card.
Note: You must use the switched fabric topology to attach the ESS to either an
xSeries or to an IBM NUMA-Q host system.
