Upgrading
the
firmware
Attention:
The firmware upgrade procedure requires the out-of-band (Ethernet)
management connections to both controllers in the connected DS4000. You can
define the controller TCP/IP addresses in the following three ways:
v
By default (to 192.168.128.101 and 192.168.128.102 for controllers A and B
respectively).
v
By a DHCP/BootP server.
v
By static definition. existing DS4000 controllers have stored TCP/IP addresses
that can be used for static definition.
Attention:
All of the enabled DS4000 premium features will be
out-of-compliance after the controller firmware upgrade. Retrieve the necessary
premium feature key files or premium feature entitlement card (to regenerate the
necessary premium feature key file) for re-enabling the premium features after
the controllers have been successfully upgraded to version 6.23.xx.xx.
Use the following procedures to upgrade a DS4000 storage subsystem manually to
controller firmware level 06.23.xx.xx:
1. If this DS4000 is part of an existing configuration with EXP100s and EXP700s
or both, the EXP100s and EXP700s must be removed from the configuration.
Perform the appropriate steps to back up the data from the EXP100s and
EXP700s before you remove them from the DS4000 configuration.
Note:
Always unmount the mapped logical drives before you power down the
DS4000 configuration and disconnect or remove the drives to ensure that
the all of the data in the server cache was flushed to the disk.
2. Power off the DS4000 configuration and the EXP810s, if applicable.
3. With the DS4000 and the EXP810s powered off, establish all fibre-channel
cabling connections and management Ethernet connections. Refer to Chapter 3,
“Cabling the EXP810,” on page 41.
Note:
Do not power on any units yet.
4. Install DS Storage Manager client software version 9.19 in the management
station.
Refer to the
DS
Storage
Manager
Version

Installation
and
Support
Guide
for
your operating system for more information on this upgrade procedure and any
system requirements.
Attention:
The management station must have an Ethernet connection to the
same network as the two controllers in the DS4000.
5. Remove controller A from the DS4000 storage subsystem.
Important:
If you do not remove controller A from the DS4000 storage
subsystem, the new firmware may not be downloaded correctly on both
controllers and the controllers will not recognize the EXP810 storage expansion
enclosure.
Refer to Appendix E, “Additional System Storage DS documentation,” on page
159 to find the appropriate guide for the location and the instructions on how to
remove the controller in a DS4000 storage subsystem.
Note:
For the DS4800 storage subsystem, controller A is the top controller
when looking at the back of the unit. For the DS4500 storage subsystem,
controller A is the top controller when looking at the front of the unit.
