DPE Model 54XX/56XX Upgrade to Model 45XX
Requirements
Requirements
• The DPE to upgrade, and each connected DAE enclosure, must
have two LCCs. (The upgrade assembly includes two Model 4400
SPs and two 800-watt SPS units.)
• If you want to upgrade to shared storage with the Access Logix™
option, you must have ordered the Access Logix option. Access
Logix Core Software ships on its own CD-ROM.
• Shared storage with Access Logix requires two Fibre Channel
switches.
• You must have the latest Interface kit to provide required
revisions of Navisphere Agent/CLI and ATF (Application
Transparent Failover).
• The operating system disk, Navisphere
® Agent, and Navisphere
Manager cannot reside on the storage system being upgraded;
that is, there must be a system disk independent of the storage
system.
• The Core Software for Model 4400 SPs does not support disks
with part number 005-44614 or 005-44299. (These are Seagate
ST19171FC 9-Gbyte half-height disks.) If the storage system you
want to convert has any such disks, replace them with a
supported model before starting the upgrade. The new Core
Software will not recognize and power up any such disks. To
verify the disk model, stop and prevent I/O to the storage
system, and then remove one disk at a time and read the part
number label on the side of the disk carrier. Then reinsert the
disk.
• If the DPE to upgrade is connected to a server running HP/UX
and it is either any FC54XX/55XX or it is an FC56XX/FC57XX
that uses Core Software earlier than version 5.11.08, then the
hardware paths to the LUNs must have been redefined. The paths
must be redefined because the newer version of Core Software
you will install supports more than eight LUNs with HP-UX. The
procedure for redefining the paths to LUNs with HP/UX is
explained in CLARiiON support note S000309A.
