1 Overview of Virtual LVI/LUN and Volume Shredder This chapter provides a brief description of Virtual LVI/LUN and Volume Shredder. • “Virtual LVI/LUN (VLL)” (page 6) • “Volume Shredder” (page 6) Unless otherwise specified, the term storage system in this guide refers to the following disk arrays: • HP StorageWorks XP24000 Disk Array • HP StorageWorks XP20000 Disk Array The GUI illustrations in this guide were created using a Windows computer with the Internet Explorer browser.
2 About Virtual LVI/LUN and Volume Shredder This chapter provides an in-depth overview of Virtual LVI/LUN and Volume Shredder. • “Overview of Virtual LVI/LUN” (page 7) • “Overview of LDEV Formatting” (page 19) • “Overview of Quick Formatting” (page 20) • “Overview of Configuring External Mainframe Volumes” (page 20) • “Overview of Volume Shredder” (page 21) Virtual LUN is a function for open systems. To use this function, you need the software called Open Volume Management.
The VLL operations include: Volume to Space, Install CV, Volume Initialize, and Make Volume. • The Volume to Space function formats one or more of the LDEVs on a selected Virtual Device (VDEV) into free space. This free space can be used to install one or more variable-sized volumes (CVs) using the Install CV function or remain as free space for future usage. • The Volume Initialize function removes all CVs under a Virtual LVI/LUN volume, and reformats the Virtual LVI/LUN volume as a VDEV.

In this manual, the sum of these two types of capacities is called the entire capacity. This section explains how to calculate the user area capacity and the entire capacity per CV. Implemented LDEVs consume this entire capacity from the VDEV capacity without exception. Therefore, even if the sum of user areas of multiple CVs and the user area of one CV are the same size, the free space generated when multiple CVs are created may be smaller than the free space generated when one CV is created.
NOTE: • ◦ The value enclosed in two upward arrows ( ) must be rounded up to the nearest whole number. ◦ The user area capacity is expressed in kilobytes ◦ The boundary value is expressed in kilobytes. The boundary value depends on the volume emulation types and RAID levels (see “Boundary Value for Each RAID Level” (page 17)).
NOTE: ◦ The value enclosed in two upward arrows ( ) must be rounded up to the nearest whole number. ◦ The user-specified CV capacity is expressed in blocks. ◦ The boundary value is expressed in kilobytes. The boundary value depends on the volume emulation types and RAID levels (see “Boundary Value for Each RAID Level” (page 17)).
NOTE: The user-specified CV capacity is expressed in blocks. To calculate the entire capacity of a CV, use the following formula. The resulting entire capacity is expressed in blocks. To convert the resulting entire capacity into megabytes, divide the capacity by 2,048. (user-specified-CV-capacity + management-area-capacity × 2) ÷ (boundary-value × 2) × (boundary-value × 2) NOTE: ◦ The value enclosed in two upward arrows ( ) must be rounded up to the nearest whole number.
NOTE: ◦ The value enclosed in two upward arrows ( ) must be rounded up to the nearest whole number. ◦ The calculated management area capacities depend on the volume emulation types and RAID levels (see “Calculated Management Area Capacities” (page 18)).

Figure 3 Parity Group Configuration As a result of VLL operations, a VDEV contains FVs, CVs, and free spaces that are delimited in logical cylinders. Sequential free spaces are combined into a single free space (see Figure 4 (page 19)). Figure 4 Virtual LVI/LUN Volume Configuration Overview of LDEV Formatting The LDEV Format feature allows you to format volumes (including external volumes). To format volumes, you must ensure that the volumes are in blocked status.
If the service processor (SVP) system option 503 is not set, when a volume is installed by using the following operations, the volume is formatted automatically: • Install CV • Volume Initialize • Make Volume If the SVP system option 503 is set, when a volume is installed by using the following operations, the volume is not formatted automatically, but is changed to Blocked. To format the installed volumes, see “Formatting the LDEVs” (page 79).
1. Zero-format the external mainframe volumes. The term zero-formatting refers to a formatting operation that writes the number 0 (zero) to the entire disk areas. For information on how to zero-format volumes, see the documentation for the mainframe system or the external storage system that you are using. 2. Use XP External Storage to perform mapping of zero-formatted external volumes and register the volumes in an external volume group.
• Volumes whose access attribute is not Read/Write • Quorum disks For details on how to execute the shredding function, see “Deleting the Data in the Target Volume” (page 90).

For details on assigning user access, see the HP StorageWorks XP24000/XP20000 Remote Web Console User Guide.
Converting Logical Volumes to Space WARNING! The Volume to Space function is a destructive operation. The data on the logical volumes being converted is lost when the operation is complete. The user is responsible for backing up the data as needed before performing this operation. The Volume to Space function allows you to convert one or more logical volumes (LDEVs) to space, which deletes the selected LDEVs from that VDEV.
6. 7. In the confirmation panel, click OK. The conversion to space starts. When the conversion ends, a message appears. Click OK to close the message. CAUTION: When the Volume to Space function is performed, the alias information that is set to the specified LDEV is also deleted. If you set the alias to the LDEV, you must migrate the alias information to another LDEV before the Volume to Space function is performed, or you must reconfigure the alias after the Volume to Space function is performed.
c. Specify the capacity of the VLL volume and/or the number of CVs according to the selected method. For example: • If you select Specify capacity and number, enter the capacity in the Capacity box, and then enter the number of CVs in the No. box. • If you select Divide free space by number, enter the number of CVs in the No. box. • If you select Divide free space by capacity, enter the capacity in the Capacity box. • If you select Set remaining space as volume, go to the next step.
11. To set other VLL volumes, repeat steps 8 through 10. To remove an LDKC:CU:LDEV number that is already assigned, select one or more VLL volume numbers corresponding to the LDKC:CU:LDEV numbers that you want to remove. Then right-click, and select Clear. 12. After setting all CU numbers and LDEV numbers, click Next. If the boundary area of the selected LDEV number does not have an SSID, the SSID setting dialog box appears. Go to step 13.
Converting CVs Back to FVs (Volume Initialize Operation) WARNING! The Volume Initialize function is a destructive operation. The data on the Virtual LVI/LUN volume being converted is lost when the operation is complete. The user is responsible for backing up the data as needed before performing this operation. The Volume Initialize function allows you to convert a Virtual LVI/LUN volume back to a fixed volume.
c. d. 5. Select an LDEV number from the white LDEV numbers in the Select LDEV Number table. The LDKC number, CU number, and LDEV number appear in the LDKC:CU:LDEV field.

When a confirmation message appears, click OK. • To remove all settings, click Clear. When a confirmation message appears, click OK.
22. To apply the changes to the storage system, click Apply (or Cancel to cancel them). While an LDEV is being formatted, a progress window is displayed. The percentage of completion displayed might be 0% or 99%. This completion percentage could remain visible while the format operation is in progress. If desired, you can make settings on the Volume Initialize function (see “Converting CVs Back to FVs (Volume Initialize Operation)” (page 74) before clicking Apply.
4. 5. Confirm that the status of the volume under the Status column of the LDEV Information table in the Customized Volume window is now changed to Blocked, and all the information for this volume is displayed in blue bold italics. Click Apply in the Customized Volume window, and then click OK on the confirmation dialog box. The new setting will be implemented on the storage system and a notification dialog box will appear to notify you that the implementation has been completed.
If volumes appear in blue bold italics on the LDEV information table, do either of the following to re-operate the volumes: • Click Apply or Cancel. • Right-click the volume displayed in blue bold italics and select Reset . Formatting All Volumes in Disk Groups or Parity Groups This section describes how to format all volumes in disk groups or parity groups.
9. Click OK to close the Format All dialog box. A message appears asking if you want to apply the settings. 10. Click OK to start formatting. Quick Formatting the LDEVs The Quick Format feature allows you to execute the quick formatting operation on internal volumes. To execute quick formatting on an internal volume, you must make sure the internal volume is in blocked status according to the instructions in “Blocking Internal Volumes” (page 85).
Table 20 Quick Format Specifications (continued) Items Description Storage system is powered off and then you turn the power back on. The Quick Format operation resumes if you turn the power back on. Restrictions • Quick Format cannot be executed on external volumes, virtual volumes, system disks, journal volumes of XP Continuous Access Journal, and quorum disks. • The XP Auto LUN feature or the QuickRestore feature cannot be applied to volumes undergoing Quick Format.
• The required time shown in Table 22 (page 83) might be as much as four times longer, depending on the configuration of disk adapter (DKA) pairs. • When you execute quick formatting at the same time on multiple parity groups that have different drive capacities, calculate the required time for the parity group that has the largest capacity. Host performance might be affected during the execution of quick formatting. Table 23 (page 84) indicates the estimated performance of a host.
the audit log in a system disk, your system disk should have 176 megabytes or more of disk capacity. The following rules apply when creating system disks: • Normal data cannot be stored in system disks. • You can create only 16 volumes for system disks in the entire storage system. • HP recommends that you create system disks in internal volumes even though you can also create system disks in external volumes. • There is no restriction on the emulation type for system disks.
4. 5. Confirm that the status of the volume under the Status column of the LDEV Information table in the Customized Volume window is now changed to Blocked, and all the information for this volume is displayed in blue bold italics. Click Apply in the Customized Volume window. The message to confirm whether to block an internal volume will be displayed. Click OK after confirming the message. Then click OK on the confirmation dialog box.
If volumes appear in blue bold italics on the LDEV information table, do either of the following to re-operate the volumes: • Click Apply or Cancel. • Right-click the volume displayed in blue bold italics and select Reset. Making External Mainframe Volumes Usable The following procedure enables you to make external mainframe volumes usable. 1. 2. 3. Zero-format external mainframe volumes.
6. Click Apply in the Customized Volume window, and then click OK on the confirmation dialog box. The new setting will then be implemented on the storage system, and a notification dialog box will appear to notify you that the implementation has been completed. Click OK on the notification dialog box. 7. Confirm that the status of the volume is now displayed as Blocked under the Status column of the LDEV Information table in the Customized Volume window. 8.
When the Format All dialog box is displayed, all entries in the Action column are Write To Control Blocks, which means that control blocks in all the disk groups or all the parity groups will be overwritten. If you change the selection in Target when any of the entries in the Action column are empty, all the entries in the Action column will change to Write To Control Blocks. 8. 9. Click OK to close the Format All dialog box. A message appears and asks if you want to apply the settings.
Format List become equal to N, the number of shredding operations, including the Last Data row. The number of rows = The number of shredding operations to perform. N = The number of shredding operations necessary to overwrite data in target volume with dummy data (see “ Calculating the Number of Shredding Operations Necessary to Overwrite Data in Target Volume with Dummy Data to Delete” (page 93)).
6. Use the Shredding Data Output dialog box to specify how Volume Shredder will save information about the result of shredding the volumes. When specifying it, see the following instructions: • To save the result of shredding a volume, you must ensure that the volume is displayed in the object Volume list. If the volume is not displayed in the list, select the volume from the non-object Volume list, and then click Add. The volume will be added to the object Volume list.
Canceling Data Deleting During the shredding operation, the following message box appears. To cancel shredding during the operation, click Cancel in this message box. Figure 30 Message Dialog Displayed During the Shredding Operation If you click Close, the progress of the shredding operation will not be displayed but the shredding operation continues. To re-display progress, click Progress in the Customized Volume window.
NOTE: Data deleting conforming to DoD5220.22-M for a volume using a flash disk is enabled by performing multiple dummy data overwriting while changing the data pattern. For the method to change the data pattern, see “Shredding Param. Dialog Box” (page 61) and “Defining the Shredding Settings” (page 89). In addition, a sample data deleting conforming to DoD5220.22-M is shown in “ Calculating the Number of Shredding Operations Necessary to Overwrite Data in Target Volume with Dummy Data to Delete” (page 93).
