IBM Host Systems will not recogonize storage systems.

Host Systems will not recogonize storage systems.  It has me stumped.

I think my issue is zoning the switch.  I’ve performed all the configuration I think I need to (firmware on drives, controllers, etc), upgraded Storage Manager 10, everything reports optimal, all cables seem OK, etc.  I’ve created the arrays, assigned logical drives, made host groups, entered in WWN’s.  

3, P520 POWER6 E4A’s

3, DS4700’s with 16, 146GB 4GBps FC drives (2 configured as hot spares). 2 systems configured as RAID10, 1 system as RAID 6.

1, 2005-B16 - Brocade - Fiber channel switch

Hi,

if you didn't configure zoning yet, this is of course your issue.

1) Decide whether to zone ports or WWNs. With port zoning, it doesn't matter if you have to replace HBAs or even complete servers (in case of defect or remodeling) as long as you use the same switch port. With WWN zoning you are free to use any port you like, the zone will "wander" with the HBA, but you will have to reconfigure the switch in case of an HBA change.

2) Log in to the switch using an administrative ID and open the "Zone Admin" application.

3) Depending on your decision made in (1) create aliases for ports or for WWNs. You will work with these aliases in the future, not ports or WWNs.

4) Create zones along a scheme like this:
One distinct zone for ( all the servers running a particular OS plus the storage server ports/WWNs these machines need ). Aliases can appear in more than one zone, but I'd recommend this only for the storage server ports/WWNs ("targets", as opposed to "initiators").
Note that this is a very basic zoning scheme, but it will suffice in most cases.
The most importatnt measure is not to intermix Unix and Windows systems in one single zone.

5) Add the relevant aliases created in (3) to these zones.

6) Create a configuration to contain your new zones. Add the zones to this config.

7) Activate your new configuration.

8) Off you go!

I presume 2005 is the year? If so once you open a web page to the switch the zoning configuration is a tiny icon in a group of 4 in the bottom left hand of the page, so easily missed. Much easier to find with the later firmware.

I'm very surprised there's only one SAN switch.

2005 is the model number. The full denomination is 2005-B16 (just as the author wrote in his question) and the marketing name is SAN16B-2. It has been withdrawn from the market some time ago, but is still fully supported by IBM.
Basically it's been an IBM branded BROCADE Silkworm product.

The neatly arranged Web GUI came with firmware level 4.x in early 2003.
