4 Provisioning storage Provisioning is the industry-standard term for providing networked storage to application servers. With HP P6000 EVA storage systems, provisioning includes the following general steps: 1. Creating one or more disk groups on a storage system. 2. Creating virtual disks within disk groups and assigning attributes, such as size and redundancy level. 3. Adding hosts as consumers of the storage on a storage system. 4.
Disk types The disk type specifies the type of physical disk drives that can be included in a disk group. The types are: Online disk type. All physical drives must be Fibre Channel or enterprise SAS drives. This disk type provides first tier performance and reliability. Near-online disk type. All physical drives are lower cost, lower performance hybrid Fibre Channel or midline SAS disk drives. Hybrid drives are dual ported, Fibre Attached Technology Adapted (FATA) drives.
Number of physical disks in a group • With online and near-online disk types, the minimum number of physical disks is 8. • With the solid state drive disk type, the minimum number of physical disks is 6. • If the number of disks is not specified when creating a disk group, the minimum is assigned. If the minimum number of disks is not available, the disk group cannot be created. • There is no maximum number of physical disks.
• Available, Vraid5. Shows the estimated capacity, if the entire disk group was used for Vraid5 virtual disks. • Available, Vraid6. Shows the estimated capacity, if the entire disk group was used for Vraid6 virtual disks. XCS 10000000 or later • Total capacity. Shows the formatted physical disk drive capacity of the disk group. • Allocated capacity. Shows the amount of disk group capacity that is being used for virtual disks. • Available capacity (estimated).
your system uses large capacity disk drives (1 TB or larger), reconstruction time may increase the risk of a second disk drive failure occurring prior to the completion of reconstruct. • Vraid6. Is optimized for speed and the highest redundancy. Vraid6 provides sufficient data redundancy to recover completely from two disk drive failures.
NOTE: In case of EVA 6100 and 8100 array models, if the number of virtual disks is more than 250, there will be a noticeable delay in displaying the Presentation tab information from the host point of view. Considerations CAUTION: Ensure that your host operating system can handle changes in volume size before you change the underlying virtual disk size. Changing the size on some operating systems can cause instability or data loss.
When unlocking a virtual disk, consider the following: ◦ Do not unlock a virtual disk that was locked by another user or by an application. For more information about using management lock, see the online help. Hosts A host is a computer that runs user applications that consume storage on a networked storage system. There are three types of hosts—Fibre Channel (FC), Fibre Channel over Ethernet (FCoE), and iSCSI.
Considerations • To access storage on a storage system, you must explicitly add a host using HP P6000 Command View or HP Storage System Scripting Utility. • A host does not have to be online to be added. After it is added, the host must be online and connected to the fabric or bridge to perform I/O to the storage system. • You can add a host by specifying an IP address (IPv4 or IPv6), a fully qualified domain name (FQDN), or a host alias.
Mirrorclone migration XCS 10000000 and later controller software supports online mirrorclone migration, which allows you to switch the identities (LUN WWNs), and thus the properties, of a source virtual disk with its synchronized mirrorclone. The migration is accomplished without impacting presentations or host I/O to the virtual disks. Data is not actually moved. The online mirrorclone migration features are part of the HP P6000 Business Copy license.
For more information on how to configure email notifications, see the P6000 Command View Online Help. You can use SSSU to view the amount of virtual disk space that is allocated and used. NOTE: SSSU displays the percentage of allocated space used. This allocation level is rounded down to the whole number.
5 Replicating storage Replication is an industry-standard term for making copies or backing up data. With HP P6000 EVA storage systems, entire virtual disks can be replicated locally or remotely using a variety of methods: • HP P6000 Business Copy (local replication). Make local copies of virtual disks using snapclones, snapshots, mirrorclones and preallocated containers. Replicated virtual disks are located on the same storage system as the source. • HP P6000 Continuous Access (remote replication).
• The redundancy (Vraid) level of a snapclone can be any level relative to the source. • Until a snapclone is normalized, another snapclone of the same source cannot be created. Snapclones cannot be created when the disk to be replicated is: • A snapshot • A disk that has a snapshot or mirrorclone • In the process of normalizing (snapclone in progress) or being deleted (P6000 Command View 10.0 or earlier) See also, “Optimizing snap creation” (page 41).
Monitoring snapshot space Demand-allocated snapshots must be able to grow as the source or snapshot is modified, otherwise all snapshots in the disk group become inoperative. As demand-allocated snapshots grow, the capacity available to create virtual disks decreases. Before you allocate space for new virtual disks, ensure that you reserve enough space for all demand-allocated snapshots in the disk group.
• XCS 10000000 and later supports online mirrorclone migration, which allows you to switch the roles of a source virtual disk with its synchronized mirrorclone. See “Mirrorclone migration” (page 34). • A mirrorclone can be presented only if the mirror link is stopped (fractured). For more information, see the HP P6000 Replication Solutions Manager Release Notes. A mirrorclone cannot be created if the intended source virtual disk is: • A snapshot or has any snapshots.
Mirrorclone states The following mirrorclone states are reported by the replication manager. Mirrorclone state Remarks Fractured There is no replication activity between the mirrorclone virtual disk and its source virtual disk. At the instant of the fracture, data on the mirrorclone is identical to its source. After a fracture, data on the two disks might no longer be identical due to host I/O to the source or the mirrorclone.
Optimizing replication performance Planning for host I/O workloads For the best snapshot and snapclone performance, create and delete snapshots and snapclones during low-demand periods for host I/O, or configure the storage system to meet performance demands during snapshot and snapclone activities. • Snapshot and synchronized mirrorclone activity is driven by the host I/O and must compete with the I/O workload on the disks.
Minimizing snapclone workloads A snapclone copies the entire source disk without stopping. However, creating a snapclone creates an additional workload on the snapclone's disk group while the data is being copied. You may observe an increase in command response time and a decrease in the disk group's maximum I/O during the copy operation. This performance impact ceases when the copy operation completes. For optimum snapclone performance: • Create snapclones during low-demand periods.
HP P6000 Continuous Access software HP P6000 Continuous Access is a licensed feature of HP P6000 EVA storage systems that enables you to: • Create DR groups and remote copies of virtual disks on two separate HP P6000 EVA storage systems. • Fail over (reverse) the direction of replication between storage systems. • Suspend and resume remote replication. • Configure various DR group parameters. NOTE: This information about HP P6000 Continuous Access software is abridged.
(only a portion of the display is shown) Creating DR groups You can use server-based HP P6000 Command View to create DR groups, remotely replicate virtual disks from one storage system to another, and perform actions. Array-based HP P6000 Command View only allows you to view DR groups that are on that storage system. NOTE: This information about HP P6000 Continuous Access software is abridged.
Fibre Channel switches typically offer two types of frame routing between N_Ports: • Source ID/Destination ID (SID/DID) routing, which transfers all exchanges through the fabric using the same path • Exchange-based routing, which transfers all frames within an exchange using the same path, but other exchanges may use alternate paths NOTE: B-class switches refer to SID/DID protocol as in-order delivery routing. C-class switches refer to SID/DID protocol as flow-based load balancing .

7 Monitoring storage system events This chapter describes how to manage events using HP P6000 Command View. Events overview Events track the progress of actions, both normal and exceptional, that occur on the storage system. Examples of typical events are creating virtual disks or initializing a storage system. Examples of exceptional events are an incomplete function or a reduction in array capabilities. Normal events are more common than exceptional events.
A normal event is informational and requires no action by you. An example of a normal event would be the controller reporting that creation of a virtual disk has completed. An example of an exceptional event would be a disk enclosure that has lost communication on a Fibre Channel loop. CAUTION: Uninitializing an array deletes all of the controller events cached in the controllers. For more information about uninitializing an array, see “Uninitializing storage systems” (page 48).
2. Select the filter parameters, and then click View Events. The following information is provided for each controller event or controller termination event: • Date/Time—The date and time that the event occurred. • Severity—The severity types are informational, critical, warning, and undetermined. • Controller—Name of the controller on which the event occurred. The name and worldwide ID of all controllers appears at the top of the event log. • Description—The text description of the event.
Viewing additional information You can view additional information for controller and controller termination events by clicking the following links in the event description: • Corrective action code • More details Corrective action code The corrective action code (CAC) shows you the recommended action to resolve the event. If the event severity is informational, the CAC is 00 and there is no corrective action to take.
3. 4. Select Configure SNMP host notification list. Click Modify host list. The Modify Host Notification window opens. 5. In the Host Name box, enter the domain name or IP address of the host.

2. Enter the evaperf fn [short] command. The fnames.conf file is created. Any friendly name information that exists for the management servers running HP P6000 Command View and listed in the fnamehosts.conf file is extracted from HP P6000 Command View and stored in the fnames.conf file, located in INSTALLROOT.
Using short names If the friendly names you created in HP P6000 Command View are impractical for the HP P6000 Performance Data Collector command line interface, you can substitute contractions for full names in the fnames.dict file. When you install HP P6000 Performance Data Collector, the fnames_sample.dict file is also installed. You can either: • Rename this file to fnames.dict and modify its contents to include the short names. • Create a separate file called fnames.dict using a standard editor.
Using the command line interface You can use the HP P6000 Performance Data Collector command line interface to display storage system performance data in a tabular format. The procedures in this section assume you are familiar with command line interfaces. Viewing storage systems To view storage systems that are visible to HP P6000 Performance Data Collector: 1. Launch HP P6000 Performance Data Collector from the desktop icon. 2.
Filtering data You can filter the data that is collected for specific items, such as a word or a host port name. For example, enter the following command: evaperf as -sz array1 array2 -fd test The output indicates where test appears on array 1 or array 2. Specifying data output in multiple files You can generate output for several commands and save the output for each command in a separate file, organized by array.
6. (Optional:) In the TLViz title box, enter a title for the TLViz-formatted files that will be generated. The formatting of the evaperf vd and evaperf pd output can be disabled by selecting either or both of the check boxes, Disable TLVIZ-VD Output and Disable TLVIZ-PD Output. If one or both of these options are checked, the corresponding TLVIZ files will not be generated. 7. Select Build TLViz files to format the data.

If friendly names are not configured a No FN message is displayed in place of the friendly name. -fofilename Copies output to a file as well as displaying it in the command prompt. You can combine this modifier with -cont and -dur for a fixed-time data capture.
located on different storage systems. The instance name indicates the storage system on which the virtual disk is located. Remote performance monitoring with Windows Performance Monitor is not supported. The binary logging feature of Windows Performance Monitor is limited in the number of HP storage system performance objects it can log simultaneously. Logging works most reliably when you log small numbers and instances of counters.
To view a description of a counter, select a counter, and then click Explain. 4. 5. 6. 7. 8. Click Use local computer counters and, in the adjacent box, select the host on which HP P6000 Performance Data Collector is running. From the Performance object box, select an object to monitor (for example, HP EVA Storage Array). Click All counters, or select counters to view. Click All instances, or select instances to view. Click Add to add the counters to the window.
This creates the evapmfilt.conf file. 4. To filter data for specific virtual disks, enter the following command with the virtual disk names: pfvd [vdisk]* You can use friendly names in these commands. 5. When filtering configuration is complete, restart Windows Performance Monitor. When you click Add counters in a new Windows Performance Monitor session, the evapmfilt.conf file is detected and data is filtered accordingly.
management, or communication with other applications. The value is always equal to or less than the % Processor Time counter and the difference is the amount of processor time engaged in non-data transfer activity. HP EVA virtual disk The virtual disk object provides information about workload and performance for each virtual disk on the storage system. Activity is reported separately for each controller accessing a virtual disk.
owning controller that must be returned to the requesting host through the proxy controller. Reported mirror traffic is always outbound from the referenced controller to the other controller. • Prefetch MB/s—The rate at which data is read from physical storage into cache in anticipation of subsequent reads when a sequential read stream is detected. Data replication initial copy data traffic for a replicated virtual disk is reported by the owning controller in the source volume prefetch statistics.
initial copy data traffic for a replicated virtual disk is reported by the owning controller in the source volume prefetch statistics. HP EVA host connection The HP EVA host connection object provides information for each HBA that has a connection to a storage system. The counters are: • Queue Depth, the average number of outstanding requests from each host adapter.
• Read Req/s—The number of read requests (per second) sent to physical disks. • Read MB/s—The rate at which data is read (per second) from physical disk. • Read Latency—The average time it takes for a disk to complete a read request. • Write Req/s—The number of write requests (per second) sent to physical disks. • Write MB/s—The amount of data written (per second) to physical disks. • Write Latency—The amount of time it takes for a disk to complete a write request.
HSV200, and HSV300 controller series, and as FP1, FP2, FP3, and FP4 for the HSV210 and HSV340 series onwards. The counters are: • Round Trip Delay—The average time, in milliseconds, for a signal (ping) to travel from the source to the destination and back. In replication traffic, the signal is queued behind data transmissions, which increases the round trip delay. If the destination controller is busy, the value also increases. Round trip delay is reported for all active tunnels.
• Log drain Req/s—The rate at which requests to remove data from the log disk owned by this DRM group to send to the destination via the DRM tunnel come in. • Log drain KB/s—The rate at which data is removed from the log disk owned by this DRM group to send to the destination via the DRM tunnel. HP EVA Xcopy Metrics The HP EVA xcopy metrics provides the summary of performance data for xcopy (extended copy) command. Each controller’s activity is reported separately.
• WSAME Dest Other Req/s —The average number of WRITE SAME requests arrived per second, where the destination LUN is owned by other controller, calculated over the polling interval. • WSAME Ave Queue Depth —Average number of WRITE SAME requests that are pending, calculated over the polling interval. • WSAME Busies/s—The average number of BUSY responses sent per second, during the polling interval, for WRITE SAME operations due to a queue full condition.

A HP array event code formats and descriptions This appendix describes how the hexadecimal number for the event code is formed. Event code format Controller and controller termination event codes appear as 32–bit hexadecimal numbers (for example, 060f4013). The bits in the event code differ slightly for each controller event type. The bits of a controller event have the following format: Table 9 HP array controller event code bits 31............24 23.........16 15........8 7........................

Glossary This glossary defines terms that are used in this guide or are related to the software. A array A synonym of storage array, storage system, and virtual array. A group of disks in one or more disk enclosures combined with controller software that presents disk storage capacity as one or more virtual disks. array-based management A management structure in which HP P6000 Command View is installed on the management module within the array controller enclosure.
J job A repeatable custom script that automates replication tasks. A job can be simple (for example, create a DR group) or complex (for example, perform cascaded replication). Jobs can be run from the GUI, from the command line, from batch files, or by a scheduler. M management server A server on which HP management software is installed. MIF Management Integration Framework. mirrorclone A copy of a virtual disk that is continually updated to reflect changes in the source.
V virtual array Synonymous with disk array and storage system, a group of disks in one or more disk enclosures combined with control software that presents disk storage capacity as one or more virtual disks. See also virtual disk. virtual disk Variable disk capacity that is defined and managed by the array controller and presented to hosts as a disk. Can be called Vdisk in the user interface.
