    Authentication is the process of using data from the LDAP server to verify a user’s name and the supplied password. Authorization is the process of using data from the LDAP server to determine the user’s group membership and rights in the system. By default, LDAP users cannot store an SSH public key using the HP 3PAR CLI setsshkey command.

    6 Managing CPGs and Virtual Volumes Overview A CPG creates a virtual pool of LDs that allows up to 4,095 virtual volumes to share the CPG's resources and to allocate space on demand. Virtual volumes draw their resources from CPGs, and virtual volumes are exported as Logical Unit Numbers (LUNs) to hosts.

Managing QoS Rules There is no limitation on the minimum number of IOPS and bandwidth that can be set on a giving VVset QoS Rule.

    NOTE: Queue depth is the average number of I/O jobs, either processing or waiting to be processed, within a polling interval. The queue depth is a non-negative integer number. When upgrading the end-to-end SAN pathing from 4 Gb/sec to 8 Gb/sec. In general, HP recommends review of the system I/O capability and adjustment of the QoS rules in use whenever a change was made to one part of the entire chain from the host to the HP 3PAR Handling Tier- 1 Applications...

    Lowering the QoS cap will result in higher I/O response times and reduced throughput on the host, and eventually queue-full errors are returned by the array to the host. NOTE: Response time is the average measured time that it takes the array to process an I/O request.

    when a queue-full message arrives at the ESXi host. This reduction in the queue length gives the array an opportunity to decrease the number of outstanding I/Os at its end. In vSphere 5.1 U1, AQD can be configured by LUN, or globally for the ESXi host. Combining QoS rules with SIOC and ADQ provides I/O congestion control on three different levels: the workload will honor the QoS limits, and it will be impacted indirectly when SIOC reacts to latency increases and when AQD responds to queue-full messages from QoS rules.

    Number of I/Os processed by QoS (including the number of I/Os Qlen delayed by QoS and number of I/Os processed by QoS without delay) You can filter by VVset by using the srstatvlun command. This can be useful in determining which VVs in a given VVset contribute the most in reaching the QoS limit.

    16 Using the HP 3PAR SNMP Infrastructure Overview In addition to managing the system with the HP 3PAR CLI, the HP 3PAR OS includes an SNMP agent that allows you to perform some basic management functions via network management software running on a management station. These SNMP management functions require that you have SNMP management software not provided by HP.

  • Page 168: Viewing Registered Managers

    Viewing Registered Managers Use the HP 3PAR CLI command showsnmpmgr to see which managers are already registered with the SNMP agent. NOTE: If the manager that monitors the system has changed, remove the old manager and register the new one. Removing a Manager To remove a manager from the agent’s list of registered managers, thus preventing that manager from receiving traps, use the removesnmpmgr command.

  • Page 169: Viewing Snmpv3 Users

    To create an SNMPv3 user, issue the createsnmpuser -p command, where: represents the password of the HP 3PAR OS local user. The password is converted to an SNPMv3 secret key. If a password is not specified with the -p option, the system prompts you to enter the password of the local user.

    17 Using mySnapshot Overview This chapter describes how to use the mySnapshot utility. The mySnapshot utility enables safe and easy copy and provisioning access to non-storage professionals such as DBAs, software developers, and test engineers working with systems. Users can safely and easily restore their own copies of test data in seconds, without relying on the storage administrator.

  • Page 171: Replacing A Read-Only Snapshot

    NOTE: The updatevv command can also update sets of virtual volumes. For a complete list of options available for the updatevv command, see the HP 3PAR Command Line Interface Reference and the HP 3PAR CLI Help. Replacing a Read-Only Snapshot The following example shows how to replace a read-only snapshot volume with a new read-only snapshot volume.
  • Page 172 NOTE: In this example, test.rw1 can have VLUNs associated with it. The command will remember the VLUN, remove the old snapshot, create a new snapshot, and recreate the VLUN with the new snapshot. After the snapshot is replaced, testuser1 must remount the filesystem on the host. In the above example, the replaced copy (test.rw1) is a new copy of the database made from the reference copy (test.ro1), and not from the database itself (test).

  • Page 173: 18 Performance Tuning

    18 Performance Tuning Analyzing and Tuning a System The tunesys command analyzes your entire system and automatically corrects space usage imbalances in the system. Virtual volume and physical disk capacity are analyzed and rebalanced for optimal performance. Access to the virtual volumes is not interrupted during the system tuning operations.

  • Page 174: Displaying Virtual Volume Space Distribution

    NOTE: Running the tunesys command does not eliminate the need to run the tunepd command. The tunesys command performs space based balancing. The tunepd command performs service time and I/O based balancing. The tunesys command verifies that LDs associated with a CPG have the same characteristics as the CPG.

  • Page 175: Thinly-Provisioned Virtual Volumes

    Thinly-Provisioned Virtual Volumes By default, TPVVs and their underlying CPGs dedicate space from all available resources as they grow, both from preexisting and new drive capacity resources. This natural expansion capability of TPVVs reduces the need for changing the layout of TPVVs after adding disks. To change the layout of TPVVs following a hardware upgrade, perform the following: Create a new CPG.

  • Page 178: Compacting Logical Disks

    If the performance of one or more physical disks degrades, the throughput of the LDs is reduced and the entire system performance may decline. There are two general reasons why a physical disk may have degraded performance: The physical disk has reached its maximum throughput due to an unbalanced load. A disk in this state typically has unusually high average service times when compared to other disks.

  • Page 179: Compacting Common Provisioning Groups

    See the HP 3PAR Command Line Interface Reference and the HP 3PAR CLI Help for detailed information about this command. Compacting Common Provisioning Groups Reclaim unused CPG space with the compactld command. CPGs provide a shared pool of LD capacity for use by all virtual volumes that draw space from that pool. If volumes that draw from a CPG are deleted, or if copy space for these volumes grows and then shrinks, the underlying LDs in the CPG pool can become less efficient in space usage.
