Enhancements
• Supports HP StorageWorks XP Continuous Access Journal Software on XP24000, XP20000,
XP12000, and XP10000 disk arrays.
• Supports HP StorageWorks XP External Storage with XP24000, XP20000, XP12000, and XP10000
disk arrays.
• Introduces new data currency configuration settings for fence level ASYNC (Journal). If this option
is selected and the XP Continuous Access Software physical link is down, XP Cluster Extension will
not perform the takeover on the S-VOL because the P-VOL potentially still holds a lot of untransmitted
data. This setting will force data currency during failover. If this option is not selected, XP Cluster
Extension will perform the takeover even if there is a potential data loss. Data consistency is still
guaranteed.
• Implements MINAP values to determine if the XP Continuous Access Software physical link is active
during takeover operations.
Fixes
• Fixes an issue in which an XP Continuous Access Synchronous Software (fence DATA) pair will
attempt to start on a P-VOL in PAIR status, but the XP Continuous Access Software physical link is
down. The first I/O to P-VOL will fence the device and application startup will fail due to I/O
errors. This version of XP Cluster Extension will now check the link status using a MINAP value
and will not allow application startup if the XP Continuous Access Software physical link is down.
• Fixes a condition in which asynchronous devices will fail over if the S-VOL is still in PAIR status,
but not when the S-VOL is in PSUE status. Normally, after a link failure, the S-VOL remains in PAIR
status for 5 minutes before the status change to PSUE. With this version, asynchronous device
groups will go online on the P-VOL side if the S-VOL is in either PAIR or PSUE status.
Prerequisites
• XP Continuous Access Journal Software can only be used on XP24000, XP20000, XP10000, and
XP12000 disk arrays.

• HP recommends XP10000/XP12000 firmware 50-09-37-00/04 or later with XP RAID Manager
