storage management software on the host, check the following:

Interface
connections
Make sure that the Fibre Channel connections to the drives are secure.
Important: After you power on the library and the Fibre Channel arbitrated
loop or fabric completes its initialization, avoid disconnecting the Fibre
Channel drives from the network. If you need to disconnect a drive from the
network, use the utility provided with your switch or hub to bypass the
affected ports before breaking the connection. The bypass sets the port to a
non-participating state on the network. After you reconnect the drive to the
library, use the utility to return the port to a participating state.
Software
installation
Make sure that your host application is installed and configured correctly (refer
to your software documentation). Pay special attention to steps that describe
how to configure the software for use with the drive(s).
Drive addressing Make sure that the drive address configured in the host application is the same
one you specified when you configured the partition containing the drive (see
Creating a Storage Partition on page 187).
Host and software
requirements
Determine whether a device driver is required. Some operating environments
require you to install device drivers before the application software can
correctly communicate with the drives. When you update the drive firmware,
you may also need to update the device driver for the drive. See Updating
Drive Device Drivers on page 496 for instructions.
