HP StorageWorks XP Remote Web Console Software - Manual (Page 56)

NOTE:
Siz supports multiple T-VOLs for each S-VOL. If you issue a pair status query to an Siz S-VOL, the status
for only one Siz pair is reported (the pair with the T-VOL with the lowest LDEV ID). To obtain the pair
status for the Siz pair(s) with the other T-VOL(s), you must direct the host query to the specific T VOL
using the T-VOL’s LDEV ID in the host command. The Siz remote console software displays the LDEV ID
and Siz pair status of all T VOLs associated with an S-VOL.
When you perform PPRC command to the Siz/URz shared volumes to query the pair status, the storage
system reports pair status of the Siz. To query pair status of the URz from the host, use XP for Business
Continuity Manager Software. Table Table 12 on page 56 lists the currency of the data on shared
Siz/URz volumes based on the Siz and URz pair status

The configuration shown is an example of a volume, which is functioning as both a Siz S-VOL and
an URz P-VOL. This configuration allows you to:
• Use Siz to provide on-site backup copies of URz P-VOLs, and/or
• Use URz to provide remote backup copies of Siz S-VOLs.
