The number of secondary volumes that can be displayed in the S-VOL List at a time is
limited to 1,024 volumes. In case the number of volumes defined in the storage system exceeds
this limit, use the Previous and Next buttons on the upper right of the S-VOL List to turn the
pages of the S-VOL List and see the entire list.
•
The Previous button allows you to return to the previous page of the S-VOL List. This button is
selectable only when the number of volumes defined in the storage system exceeds 1,024 volumes,
which is the maximum number of volumes that can be displayed on one page. The button is
grayed out if the total number of volumes defined in the storage system is less than 1,024 volumes.
•
The Next button allows you to turn to the next page of the S-VOL List. This button is selectable
only when the number of volumes defined in the storage system exceeds 1,024 volumes, which is
the maximum number of volumes that can be displayed on one page. The button is grayed out if
the total number of volumes defined in the storage system is less than 1,024 volumes.

The S-VOL List displays the following information related to S-VOLs:
• Volume: Information about the volume is displayed in AAA-BB-CCC(XX:YY:ZZ) format.

• BB: The group number of host group
• CCC:

number
• XX:YY:ZZ: LDKC number:CU number:LDEV number
Note:
An LDEV number that ends with a # mark indicates that the LDEV is an external volume
(for example, 00:00:01#). An LDEV number that ends with a letter X indicates that the LDEV is
a virtual volume used by XP Thin Provisioning (for example, 00:00:01X). For details regarding
the external volumes, see the HP StorageWorks XP24000 External Storage Software User’s
Guide. For information about Dynamic Provisioning, see the HP StorageWorks XP24000 Thin
Provisioning Software User's Guide.
