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 5) • “Volume Shredder” (page 5) Unless otherwise specified, the term storage system in this guide refers to the following disk arrays: • HP XP24000 Disk Array • HP 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 6) • “Overview of LDEV Formatting” (page 18) • “Overview of Quick Formatting” (page 18) • “Overview of Configuring External Mainframe Volumes” (page 19) • “Overview of Volume Shredder” (page 19) 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.

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. For detailed information, see “Formatting the LDEVs” (page 70).
• Journal volumes • Volumes for a system disk • Quorum disks Overview of Configuring External Mainframe Volumes To use external volumes with the storage system, usually you must use HP XP External Storage Software to perform external volume mapping, and then use the Format command of Virtual LVI to format the volumes (see “Formatting the LDEVs” (page 70)). However, when you format external mainframe volumes in this way, the formatting operation may take some time.
Therefore, HP recommends that you overwrite a volume at least three times using dummy data. The default setting of Volume Shredder defines three times of overwriting using dummy data. If you change the setting, you can overwrite the volume up to eight times. For details on the setting of Volume Shredder, see “Defining the Shredding Settings” (page 81).

However, the number of parity groups that have not undergone and can undergo Quick Format does not increase.
Table 22 Estimated Required Time for Quick Formatting (continued) Capacity of a Drive (GB) Required Time (hours) 750 17.5 1000 23.5 • Table 22 (page 74) indicates the required time when you execute quick formatting on all the areas in a parity group. When you execute quick formatting on some volumes in a parity group, the required time may be less than the time indicated in Table 22 (page 74).
The required system disk capacity is as follows: • Capacity for Quick Format management information: 46 MB, which means 66 cylinders if the track format is 3380; or NF80, which means 55 cylinders if the track format is 3390. • Capacity for the audit log buffering area: 130 MB, which means 185 cylinders if the track format is 3380; or NF80, which means 154 cylinders if the track format is 3390.
• It has been about an hour and a half since the disk system firmware has been updated. • It has been about an hour and a half since the storage system has been restarted while a Quick Format operation was being performed and data in shared memory was being deleted (volatilized). • It has been about an hour and a half since the Quick Format operation was completed for the first time • The system disk is being used for the Audit Log Buffer function.
5. 6. 7. 8. Click Apply in the Customized Volume window, and then click OK on the confirmation dialog box. VLL starts preparing for quick format and shows a message (Figure 29 (page 78)). When the progress reaches 100%, a notification dialog box will appear to notify you that preparing for quick formatting has been completed. Click OK on the notification dialog box.
• Volume Initialize • Make Volume If an external volume to be operated is disconnected, the external volume must be omitted from the operation target. Overwriting Control Blocks in Specific External Volumes To overwrite the control blocks of a specific external volume: 1. See “Making External Mainframe Volumes Usable” (page 78), and then take steps 1 to 2 in that section. 2. Make sure that Remote Web Console is in Modify mode.
1. 2. See “Making External Mainframe Volumes Usable” (page 78), and then take steps 1 and 2 in that section. Make sure that Remote Web Console is in Modify mode. For detailed information about Modify mode, see the HP XP24000/XP20000 Remote Web Console User Guide. 3. 4. 5. 6. In the Customized Volume window (“Customized Volume Window” (page 24)), click Format All. The Format All dialog box appears. In Action, select Write To Control Blocks. Make sure that Parity Group Type is External.
Defining the Shredding Settings To execute a shredding operation without using the default settings, use the Shredding Param. dialog box to define your shredding settings, which will be used to delete the data from the volumes. To define the shredding settings: 1. Make sure that Remote Web Console is in Modify mode. For detailed information about Modify mode, see the HP XP24000/XP20000 Remote Web Console User Guide. 2. 3. Click Shredding Param.
NOTE: To delete a row from the Format List, select the row, and click Delete. You cannot delete the row that is defined as Last Data. Deleting the Data in the Target Volume To execute a shredding operation to delete data from volumes: 1. Make sure that Remote Web Console is in Modify mode. For detailed information about Modify mode, see the HP XP24000/XP20000 Remote Web Console User Guide. 2.

If you have not chosen to download the file, the confirmation dialog box for the completion of the shredding operation is closed. When the shredding operation is finished, the status of the volume will be automatically changed to Normal.
Time required to overwrite data in the target volume with dummy data The time required to overwrite data in the target volume with dummy data (the worst case) depends on the model of the data-deleting target volume and the time to overwrite with dummy data. • Given this model of the data deleting target volume: RAID configuration: 7D+1P • The time required for overwriting data in the target volume with dummy data is the following.
Calculating the Number of Shredding Operations Necessary to Overwrite Data in Target Volume with Dummy Data to Delete When a flash disk is used, space is newly allocated in response to a write request and the target volume to delete data is converted to space. For this, data deleting by overwriting data using the data exceeding the capacity of target volume is required. Procedures to calculate the number of shredding operations necessary to overwrite data in the target volume with dummy data are as follows.
