3par inserv physical reference manualFor example, the configured used and free space information for the storage system. You can obtain performance and storage utilization statistics on the following storage objects: Controller Nodes Common Provisioning Groups(CPGs) Disk Cages and applicable interfaces, power supplies, and fans Physical Disks Logical Disks Ports Virtual Volumes The probe configuration is available only through the Admin Console. Contents Revision History This section describes the history of the revisions for this probe.: Support case(s) may not be viewable to all customers. Support case numbers 816725, 716511 GA August 2017 Fixed Defect: When a volume listed in the system is renamed, the probe displayed both the renamed as well as the original volume. Support case number 610470 GA July 2017 Fixed Defects: The probe intermittently generated incorrect alarms. Support case number 460996 Improved the probe performance. Support case number 433600 The probe did not validate the port number when connecting to the storage system. Support case number 229882 GA November 2016 GA April 2016 The probe configuration is available ONLY through Admin Console GUI and NOT through the Infrastructure Manager (IM) GUI. The probe includes the standard static alarm threshold parameters. - June 2015 You must start the CIM server on your system to enable communication between the probe and the HP 3PAR storage system. Update the NAS Probe Alarms are classified by their subsystem ID, identifying which part of the system the alarm relates to. These subsystem IDs are kept in a table maintained by the NAS probe. If you are working with CA UIM 8.2, you must add the following subsystem IDs manually using the NAS Raw Configuration menu. However, if you have upgraded to CA UIM 8.31 or later, then you do not have to manually add the following subsystem IDs: Click Subsystems. Add the new key name and value. Repeat this process for all of the required subsystem IDs.http://foundrygate.com/userfiles/4-star-40-manual.xml

Ensure that you enter the key names as-is including the period (.) in the end for correct mapping. The term “Broadcom” refers to Broadcom Inc. For each asset type acquired by Cloud Insights, the most common terminology used for this asset is shown. When viewing or troubleshooting this data collector, keep the following terminology in mind: The default is 40 minutes. The default is 300 seconds. Provider initialization failed. Try changing the array name. When communication from the SP to the node If the process takes longer than twenty minutes, problems When complete, the node reboots.

You interact with it in exactly the same way you would a physical 3Par i.e. via the HP 3PAR Management Console or remote CLI. Most of the major features including AO, DO, snapshots, exporting virtual volumes and even remote replication (if you have 2 instances of the simulator) are supported. I have covered the high level steps to install the simulator to give you a feel for the process below, for detailed step by step instructions refer to the release notes that come with the simulator. The first NIC will be the IP you use to manage the device when using the management console or CLI. The second you will not need unless you are using RCIP. The third will be connected to a local private network allowing the 3 VM’s to talk to each other The default choices are:Was wondering about updating the InServ. It is not currently possible to run an upgrade on the simulator. You cannot create a LAN segment network. Creating a private network (with no host connection and manually configured 192.168.101.0 network) didn?t work. The problem is that after step 1 “Simulator Cluster Node configuration” on both nodes after reboot the network is not working and step 2 fails with an error (cluster is not formed).http://www.tsjikatilo.be/UserFiles/4-steps-of-manual-handling.xml What did you do to fix this. I have set it up as per the reference guide. I’ve tried it on two different PCs now and it just doesn’t work for me. VMware workstation is supported, just try following the instructions carefully I’ve got v1.2 but you have to change the system date to pre feb 2014 on the host which is a pain. I am running V2.0 I see you stated to contact Ivan on twitter. DM’s aren’t possible if Ivan isn’t following me. With that being the case, is it okay to ask him via tweet. Just want to make sure that I won’t cause any problems by asking him that way. I followed the steps in the pdf. When I’m at the Out of the box steps, it takes a couple minutes and it gives a message saying Cannot create admin volume. If you choose more than 48 disks it will not work. Try choosing one of the default cage options form the enclosure VM eg 1. 1 cage, 24 HDDs 1 DCN1 cage with 24 FC drives I redid about 3 times, always the same things, and it worked.Really practical to play with it since I don’t have a 3par anymore. The ESD seems to have come up and now I have done the simulator step where I choose the node number and assign it a serial number. The nodes reboot and they give my the following error message: Suggest giving it another go I am going to take an exam next week from 3PAR. So I would like to learn some hads-on. Thank you in advance, Flaszkan Ella Please read the article again, the instructions are in thereyou need to follow Ivan on twitter and request. Good luck with the Exam! I hope he will answer. Flaszkan Not just asking you to trust it on first use? I am getting the same error. Access is via connecting on Twitter, read the article again and you will see all the info Can you please paste the here to download it. The Simulator is accessed via Twitter, please read through the above post for details Is it possible to expose iSCSI? These are only used for the fake hosts to connect to.http://www.drupalitalia.org/node/67607 If you are struggling with an error suggest, deleting the VM’s and carefully following the instructions again from the start again. I configured an ipadresse for esd and can login via putty. But can’t login trought the cli or management console? I forgot to ran the OOTB setup ?? I ran it, now I can connect en start to play. Thnx I’ve also tried to find it on the HPE website but only yhe P6000 EVA Simulator shows up. It is currently just available to partners. I will update the post if this changes again. Thank you for the update. Please contact your local HPE representative. However, I am getting this error “Trying to build up link to node 0” and after that, no positive results. Please guide how to resolve this. If this does not work I would suggest starting again following each step carefully.Please let me know what might have gone wrong.

Most of the time you will never require this but on occasion during a power outage or planned Datacenter shutdown the need could arise to turn on and off your 3PAR storage system. Enjoy the process after the jump. Using improper tools can result in damage to the storage system. Attach the grounding strap clip directly to an unpainted surface of the rack. If the system was powered off abruptly, powering on could take considerably longer. This can seriously impact host access to data. Thin provisioning allows the array to allocate storage only when it is used. A space saving in excess of 50 is quite common. The rest of the storage does not need to be installed until it is going to be used; on some systems the space is never completely used, and the extra storage never needs to be purchased at all. This in turn can cut energy consumption and the production of greenhouse gasses while saving on capacity and energy costs. Also, when existing data is erased correctly, space can be reclaimed and will be reused in preference to requesting additional storage space. No disk is overworked in comparison to another, so no maintenance “hot spots”. This is particularly good for virtualised server infrastructures such as VMWare.

Warranty WARRANTY STATEMENT: To obtain a copy of the warranty for this product, see the warranty information website: Federal Communications Commission Radio Frequency Interference Statement WARNING: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user s authority to operate the equipment. This device complies with Part 15 of FCC Rules. Operation is subjected to the following two conditions (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Canadian Compliance Statement This ClassA digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations. They are intelligent, compact, extremely dense storage units where each is capable of holding a large number of disk drives in a small rack space (EIA-standard rack units). The HP 3PAR StoreServ Storage is housed in 2 meter (2M) cabinets and is comprised of the following components: Controller nodes are high-performance, data movement engines that provide the caching capabilities and manage the flow of data in a storage system. The Storage system can accomodate two or four controller nodes while the can accommodate two, four, six or eight nodes. The 3PAR Storage backplane works in conjunction with the controller nodes to route data. This passive, full-mesh backplane enables high-bandwidth and low-latency internal pathing that supersedes bus-, switch-, and even InfiniBand-based architectures. The Drive Chassis houses the drive cages that, in turn, contain the drive bays. Each drive bay contains one magazine that can hold four hard disk drives. Fibre Channel adapters and FC-AL modules provide high speed routing of data and enable granular and potentially massive connectivity to hosts and to the drive chassis. The Service Processor provides the remote error detection and reporting capabilities that support diagnostic and maintenance activities for storage systems. In general, one Service Processor (SP) s required per storage system.

Enhancing Security with Data Encryption When a Data Encryption license is registered, you must manually enable the encryption feature on the system. When the encryption feature is enabled successfully, all the drives in the system become automatically set in an encrypted state. You can review the encryption status of individual hard disk drives within the system Summary tab of the HP 3PAR Management Console. This feature allows you to perform the following encryption-related tasks: Check encryption status Enable encryption Back up an authentication key Restore an authentication key Generate a new key Recover a key For more information about enabling the feature, see the HP 3PAR Management Console User s Guide. CAUTION: HP recommends retaining all acquired software product licenses for reference and maintenance purposes. The maximum number of supported drive chassis varies according to the number of controller nodes utilized by the system. The physical and capacity specifications are shown here. The efficiency value is based on a host-maximized configuration using 600GB drives. NOTE: SSDs have a limited number of writes that can occur before reaching the SSD's write endurance limit. This limit is generally high enough so wear out will not occur during the expected service life of an HP 3PAR StoreServ under the great majority of configurations, IO patterns, and workloads. HP 3PAR StoreServ tracks all writes to SSDs and can report the percent of the total write endurance limit that has been used. This allows any SSD approaching the write endurance limit to be proactively replaced before they are automatically spared out. An SSD has reached the maximum usage limit once it exceeds its write endurance limit. Following the warranty period of the SSDs, the SSDs that have exceeded the maximum usage limit will not be repaired or replaced under HP support contracts.
