1 Overview of Volume Security

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

• HP StorageWorks XP12000 Disk Array

• HP StorageWorks XP10000 Disk Array

The GUI illustrations in this guide were created using a Windows computer with the Internet Explorer browser. Actual windows may differ depending on the operating system and browser used. GUI contents also vary with licensed program products, storage system models, and firmware versions.

Overview

Volume Security protects data in your HP storage system from I/O operations performed at mainframe hosts. Security can be applied to logical volumes so that specified mainframe hosts are unable to read from and write to the specified logical volumes. Volume Security also enables you to prevent data on logical volumes from being accidentally overwritten by erroneous local or remote copy operations.

Volume Security can be used in conjunction with the Volume Security Port Option. This optional program is used to specify storage system ports through which hosts can access logical volumes.

Using Volume Security you can manipulate up to 64 hosts and 65,280 logical volumes for one storage system. Volume Security also enables you to create up to 64 security groups, 64 host groups, and 64 Volume Groups for one storage system.

Volume Security operations are performed using the licensed HP StorageWorks XP Remote Web Console software. The Remote Web Console software communicates directly with the storage system via a local-area network (LAN). Remote Web Console displays detailed Volume Security information and allows you to configure and perform Volume Security operations for the mainframe systems data stored on the storage system. For further details, see the HP StorageWorks XP24000/XP20000 Remote Web Console User’s Guide.

To apply port-level security, you must install the Volume Security Port Option. Before installing this program, ensure that Volume Security is already installed. For details on the installation procedure, see the HP StorageWorks XP24000/XP20000 Remote Web Console User’s Guide.

Terminology

There are a few notes regarding terminology that users should be aware of when using this manual:

• In the storage system documentation, logical volumes are sometimes referred to as logical devices

(or LDEVs). Also, the storage system documentation sometimes uses the term, LDEV security to refer to security policy that volume security enables you to apply to logical volumes.

• In the Hitachi TrueCopy™ for Mainframe User's Guide, primary volumes are often referred to as

M-VOLs, or main volumes. Also, secondary volumes are often referred to as R-VOLs or remote volumes. In the Hitachi ShadowImage™ for Mainframe User's Guide, primary volumes are often

XP24000/XP20000 Volume Security User's Guide 7

referred to as S-VOLs, or source volumes. Secondary volumes are often referred to as T-VOLs, or target volumes.

Overview of Volume Security8

2 About Volume Security Operations

Overview of Volume Security Functions

The Volume Security feature protects data in your storage system from I/O operations performed at mainframe hosts. Volume Security enables you to apply security to volumes so that the specified mainframe hosts will be unable to read from and write to the specified volumes. Volume Security also enables you to prevent data on volumes from being overwritten by erroneous copy operations.

Volume Security can be used in conjunction with an optional program Volume Security Port Option. This optional program can be used to specify storage system ports via which hosts can access volumes.

In the storage system documentation, volumes are sometimes referred to as logical devices (or LDEVs). Also, the storage system documentation sometimes uses the term LDEV security to refer to security policy that Volume Security enables you to apply to volumes.

Protecting Volumes from I/O Operations at Mainframe Hosts

Volume Security enables you to protect volumes from unauthorized accesses by mainframe hosts. To protect volumes from unauthorized accesses, you must create security groups and then register mainframe hosts and/or volumes in security groups. Security groups are classified into access groups or pool groups. To allow some (but not all) mainframe hosts to access volumes, you must classify the security group as an access group. To prohibit all mainframe hosts from access volumes, you must classify the security group as a pool group.

Enabling Only the Specified Hosts to Access Volumes

To allow only some mainframe hosts in your network to access volumes, you must register the mainframe hosts and the volumes in an access group. For example, if you register two hosts (host_A and host_B) and two volumes (vol_C and vol_D) in an access group, only the two hosts will be able to access vol_C and vol_D. No other hosts will able to access vol_C and vol_D.

If mainframe hosts are registered in an access group, the hosts will be able to access volumes in the same access group, but will be unable to access other volumes. For example, if you register two hosts (host_A and host_B) and two volumes (vol_C and vol_D) in an access group, the two hosts can access vol_C and vol_D and cannot access other volumes.

To register hosts in an access group, you must create a host group, register the hosts in the host group, and then register the host group in the desired access group. To register volumes in an access group, you must create an LDEV group, register the volumes in the LDEV group, and then register the LDEV group in the desired access group. Any access group can only contain one host group and one LDEV group.

In Figure 1, six mainframe hosts are attached to a storage system and two access groups are created. Here, the following security settings are applied:

• The volumes ldev1 and ldev2 are accessible only from host1, host2, and host3 because the two

volumes and the three hosts are registered in the same access group.

XP24000/XP20000 Volume Security User's Guide 9

• The volume ldev4 is accessible only from host4 because ldev4 and host4 are registered in the

same access group.

• The volume ldev5 does not belong to any access groups. For this reason, hosts in access groups

cannot access ldev5. ldev5 is only accessible from host5 and host6, which are not registered in access groups.

Figure 1 Security Example 1

Port-Level Security

Usually, hosts are connected to two or more ports via cables and have access to volumes via these ports. In the security example in Figure 1, hosts in access groups can access volumes via every port to which the hosts are connected.

Note, however, that Volume Security Port Option enables you to prohibit hosts from accessing volumes via specified ports. For example, if a host named host1 is connected to two ports port1 and port2, you can permit the host to access volumes via port1 and prohibit the host from accessing volumes via port2.

Port-Level Security Implementation

To implement such port-level security, first you must determine ports via which hosts can access volumes, and then you must register the ports in host groups. For example, if you register host1 and port1 in the same host group named hg1 and then register hg1 in an access group, host1 can access volume via port1 but cannot access volumes via port2.

In Figure 2, the following security settings are applied:

• The hosts host1, host2, and host3 can access the volumes ldev1 and ldev2 via port1, port2, and

port3. However, the hosts cannot access the volumes via other ports.

• The host host4 can access the volume ldev4 via port4. However, the host cannot access the volume

via other ports.

About Volume Security Operations10

Figure 2 Security Example 2

If no ports are registered in a host group, hosts in the host group can access volumes via ports to which the hosts are connected.

This manual uses the term port-level security, which is a security policy for enabling hosts to access volumes only via ports registered in host groups and thus prohibiting hosts to access the volumes via other ports.

CAUTION:

Before you apply security, you should confirm what hosts are performing I/O operations on volumes in access groups. If any hosts perform I/O operations on volumes in access groups that the hosts do not belong to, you will need to stop the I/O operations before you apply security. For example, if you attempt to apply security settings illustrated in Figure 2, an error occurs and the attempt fails if

host4

and

host5

to ensure that

are performing I/O operations on

host4

and

host5

are not performing I/O operations on

ldev1

Prohibiting All Hosts from Accessing Volumes

To prevent all the mainframe hosts from accessing volumes, you must register the volumes in a pool group (Note that you do not need to register hosts in pool groups). For example, if you register two

. To apply the security settings, you will need

ldev1

XP24000/XP20000 Volume Security User's Guide 11

volumes (vol_A and vol_B) in a pool group, all the mainframe hosts connected to your storage system will be unable to access vol_A and vol_B. To register volumes in a pool group, you must create an LDEV group, register the volumes in the LDEV group, and then register the LDEV group in the desired pool group. Any pool group can only contain one LDEV group.

In Figure 3, a pool group is created. Volumes in this pool group (that is, ldev7, ldev8, and ldev9) are inaccessible from all the hosts:

Figure 3 Security Example 3

Protecting Volumes from Erroneous Copy Operations

When storage system copy software (TrueCopy for Mainframe, Universal Replicator for Mainframe, ShadowImage for Mainframe, and HP StorageWorks XP for FlashCopy Mirroring Software or XP for FlashCopy Mirroring V2 Software) is used to perform copy operations, data will be overwritten onto the secondary volumes (that is, the copy destination volumes). If a volume containing important data is specified as a secondary volume (that is, the copy destination volume) by mistake, storage system copy software operations can overwrite important data on the volume and you could suffer loss of important data.

Volume Security enables you to avoid such loss of data. If a volume contains data that should not be overwritten, you can prevent the volume from being used as a secondary volume (that is, the copy destination volume).

Secondary volumes (that is, copy destination volumes) are often referred to as remote volumes or R-VOLs in the Hitachi TrueCopy™ for Mainframe User's Guide. Also, secondary volumes are referred to as target volumes or T-VOLs in the Hitachi ShadowImage™ for Mainframe User's Guide.

Warnings Regarding Volume Security

Do not apply security to volumes on which any job is running. If you apply security to such a volume, the job will possibly end abnormally.

About Volume Security Operations12

When applying security, make sure that your security settings are correct. If incorrect security settings are made, the system will be difficult or impossible to control.

If the CPU of a mainframe host is upgraded after you apply security settings, you must execute the system command D M=CPU at the mainframe host to obtain the latest information about the host. Next, you must use the latest information to update host information in the Add/Change Host dialog box (for details, see “The Add/Change Host Dialog Box” on page 27).

If you do not update host information, the system will be impossible to control.

• If you are using storage system copy software (TrueCopy for Mainframe, Universal Replicator for

Mainframe, ShadowImage for Mainframe, and XP for FlashCopy Mirroring or XP for FlashCopy Mirroring V2): When you use Volume Security to make security settings, you must register the

primary volume and the secondary volume (that is, the copy source volume and the copy destination volume) in the same LDEV group. For details on how to register volumes in LDEV groups, see

“Registering Volumes in an LDEV Group” on page 51 or “Registering Volumes in an LDEV Group” on page 54.

If you apply security to a primary volume (that is, copy source volume) of a pair of storage system copy software, some or all mainframe hosts might become unable to read from and write to the primary volume. However, the copy operation will be performed normally; data will be copied from the primary volume to the secondary volume.

If you register a primary volume or secondary volume in a security group and then make a setting for preventing the volume from being used as a secondary volume, this setting will take effect after the pair is split.

Mainframe hosts cannot access volumes in pool groups. If a volume in a pool group is specified as a primary volume, the pair creation command might fail.

In the Hitachi TrueCopy™ for Mainframe User's Guide, primary volumes (that is, copy source volumes) are often referred to as M-VOLs or main volumes. Also, secondary volumes (that is, copy destination volumes) are often referred to as R-VOLs or remote volumes.

In the Hitachi ShadowImage™ for Mainframe User's Guide, primary volumes (that is, copy source volumes) are often referred to as S-VOLs or source volumes. Also, secondary volumes (that is, copy destination volumes) are often referred to as T-VOLs or target volumes.

• If you are using Virtual LVI/LUN (VLL) volumes:If you apply security to a VLL volume, you will be

unable to change the VLL settings on the volume. To change the VLL settings, you must use Volume Security to disable security on the VLL volume. For details on how to disable security, see

“Disabling Volume Security” on page 58.

• If you are using HP StorageWorks XP for Compatible Parallel Access Volumes Software: If you

apply security to a Parallel Access Volumes base volume, the security settings will also apply to the corresponding alias volume.

• Removing secured volumes:If you apply security to a volume, you will be unable to remove the

volume. To remove the volume, you must disable security on the volume. For details on how to disable security, see “Disabling Volume Security” on page 58.

• Removing PCBs with secured ports: If port-level security is applied to your storage system, you

cannot remove the PCBs (printed circuit boards) that include secured ports. To remove PCBs that include secured ports, you must use Volume Security Port Option to disable security on the ports. For details on how to disable security, see “Deleting Ports from Host Groups” on page 63.

Supported Volume Emulation Types

• Volume emulation types (that is, device emulation types): Volume Security supports the following

volume emulation types:

• 3380-3, 3380-3A, 3380-3B, 3380-3C

• 3390-3, 3390-3A, 3390-3B, 3390-3C, 3390-3R

Maximum Possible Number of Groups

Volume Security enables you to create up to 128 security groups per storage system, and up to 64 security groups per LDKC. Security groups are classified into access groups and pool groups:

• One access group can contain only one host group and one LDEV group. One host group can

contain up to 32 hosts. One LDEV group can contain up to 65,280 volumes.

• One pool group can contain only one LDEV group. One LDEV group can contain up to 65,280

volumes.

The maximum possible number of host groups is 128 per storage system, and 64 per LDKC.

The maximum possible number of LDEV groups is 128 per storage system, and 64 per LDKC.

Maximum Possible Number of Hosts and Volumes

Volume Security allows you to manipulate up to 128 hosts for storage system, and up to 64 hosts per LDKC. Volume Security enables you to manipulate up to 130,560 volumes per storage system, and up to 65,280 volumes per LDKC.

3 Using the Volume Security GUI

This chapter explains Volume Security window and dialog boxes.

The Volume Security Window

The Volume Security window (Figure 4) appears when you start Volume Security. This window is the starting point for all the Volume Security operations.

To start the Volume Security software:

1. Log on to the disk array to open the Remote Web Console main window. For details, see the HP

StorageWorks XP24000/XP20000 Remote Web Console User’s Guide.

2. Click Go, Mainframe Connection, and then select Volume Security on the menu bar of the Remote

Web Console main window.

• To make security settings and apply the settings, you must use a user account that has the write

permission (For example, the Administrator account). If you use a user account that does not have the write permission, you will be able to view security settings but will neither be able to make security settings nor apply security settings.

• To set security using Volume Security, you must make sure that Remote Web Console is in Modify

mode. For detailed information on how to do this, see the HP StorageWorks XP24000/XP20000 Remote Web Console User’s Guide.

DescriptionItem

When creating a new security group, you enter the name of the security group in this Enter Security Group text box. When renaming an existing security group, you select the security group

in the Security Group List table and then enter a new name. The following conventions apply to security group names:

• Up to eight characters can be used.

• Characters are case-sensitive.

• The following characters cannot be used:

\ , / : ; * ? " < > |

• The first character and the last character must not be a space.

Select to make no changes, enable, or disable security settings. The default is Enable.

• No Change does not change the security status of the security groups selected in the Security

Group List table. For example, if you select a security-enabled group and a security-disabled

group in the table, Disable disables security settings in both groups, but No Change does not change the current security status for both groups (The former remains security-enabled and the latter remains security-disabled).

• Enable enables the security settings that are made in the security groups selected in the Se-

curity Group List table.

CAUTION:

It is possible that security settings are disabled even if Enable is selected. If Access is selected in the Group Status box (see below) and the security group contains neither a host group nor an LDEV group, security settings in the security group are disabled unconditionally.

Group Status

T-VOL/RVOL

• Disable disables the security settings that are made in the security groups selected in the Se-

curity Group List table.

Sets a selected security group as access groups or pool groups. The default is Access.

• No Change does not change the group status of the security groups selected in the Security

Group List table. For example, if you select one access group and one pool group, Access

changes the two groups into access groups, but No Change does not change the two groups (The former remains an access group and the latter remains a pool group).

• Access specifies the selected security groups as access groups. Volumes in an access group

can only be accessed by hosts registered in the same access group but cannot be accessed by other hosts.

• Pool specifies the selected security groups as pool groups. Volumes in a pool group cannot

be accessed by any hosts.

Specifies whether volumes in the security group can be used a secondary volumes (i.e., copy destination volumes). The default is Enable.

• No Change does not change the secondary volume settings of the security groups selected

in the Security Group List table. For example, if volumes in one of the selected security groups are usable as copy destinations, but volumes in the other security group are unusable, Enable makes volumes in both groups usable as destinations. However, No Change does not change volumes in both groups (The former remains usable, and the latter remains unusable).

• Enable makes volumes in the selected security groups usable as secondary volumes (copy

destinations).

• Disable makes volumes in the selected security groups unusable as secondary volumes (copy

destinations).

5 Troubleshooting

Troubleshooting Volume Security

The Error Detail dialog box (Figure 22) may appear when you attempt to apply security settings. The probable causes of the error are:

• Some hosts in one security group are accessing volumes in another security group.

• Some hosts do not belong to any security group, but the hosts are accessing volumes in a security

group.

To remove this error, you must find the hosts and the volumes that cause the error. To find them, take the following steps:

1. In the Error Detail dialog box, click the arrow button at the right end of the Host drop-down list.

• If the drop-down list displays only one entry, only one host is causing the error.

• If the drop-down list displays two or more entries, two or more hosts are causing the error.

2. Select a host from the Host drop-down list.

3. Right-click the arrow button at the right end of the CU drop-down list, and then check how many

CU images are displayed in the drop-down list.

• If the drop-down list displays only one entry, the table displays all the volumes that are causing

the error.

• If the drop-down list displays two or more entries, some of the error-causing volumes are dis-

played in the table. To view other error-causing volumes, use the CU drop-down list to specify another CU image.

4. If two or more hosts are causing the error, repeat steps 2. to 3.

If error-causing hosts and volumes are detected, do either of the following to remove the error:

• Vary the error-causing volume offline from the error-causing host. For detailed information about

varying the volume offline, see the documentation for host commands.

• Find the security group that contains the error-causing hosts and the error-causing volumes. Next,

disable the security settings of the security group (see “Disabling Volume Security” on page 58).
