Virtual or physical drive requirements • Maximum of 5 drives • Minimum size: 5 GB Hard drives, either virtual or physical • Maximum size: 2040 GB Virtual hard drives window Select up to 5 virtual hard drives and designate the size. Physical Drives window Select up to five physical drives that you have prepared, and which are offline.
Installing the P4000 VSA for Hyper-V
4 Getting started with the P4000 SAN Installing the CMC Install the CMC on the computer or virtual machine that you use to administer the VSA. You administer the entire network of VSAs from this CMC. The CMC installer is located in the directory where you unzipped the VSA zip package. If you imported the VSA for ESX Server using the OVF package, you must download the SAN/iQ Management SW DVD, which includes the CMC. Download the DVD from the website: www.hp.
Getting started with the CMC • Open the CMC. If you are opening the CMC for the first time, and have not already discovered storage systems on the SAN, the Find Wizard opens automatically. Figure 2 Opening the CMC for the first time . • Click Next and proceed through the Find Nodes Wizard. The wizard guides you through the steps for finding the VSA on your network. After finishing the wizard, the VSA appears in the navigation window in the Available pool. Figure 3 Newly found VSA in CMC .
1. Configure monitoring , RAID, and network from these categories Figure 4 Configuring the hardware . Configuring RAID Configure RAID after powering on the VSA. If you power off the VSA and add disks, you must again configure RAID when you power on the VSA. NOTE: If you create the VSA for Hyper-V with one disk, RAID will be automatically configured. If you create the VSA for Hyper-V with more than one disk, you must manually add the remaining disks to RAID using the CMC. 1.
4. Select RAID (virtual) from the list and click OK. CAUTION: VSA for ESX Server only. If you have trouble configuring RAID now, you may have made a mistake when configuring a virtual disk earlier. On the ESX Server, verify that the VSA has at least one virtual disk. The first virtual disk must be configured on SCSI 1:0. Additional disks must be configured sequentially on SCSI 1:1 through 1:4.
Use the Management Groups, Clusters, and Volumes wizard to create your storage pool. For information about using the wizards, see Chapter 1, “Getting Started,” the section “Creating Storage by Using the Getting Started Launch Pad” in the HP StorageWorks P4000 SAN Solution user guide or in the Online Help. Troubleshooting Table 6 Troubleshooting—ESX version Problem You want to reinstall the VSA Solution 1. Close your CMC session. 2. In the VI Client, power off the VSA. 3.
Problem You want to see your VSA, but the window is black. Solution • You are in the console view of the guest window. Change to the Summary view. • Your console window has timed out. Click in the window with the mouse and then press the Backspace key. Table 7 Troubleshooting—Hyper-V version Problem Solution Using the Hyper-V Manager: You want to reinstall the VSA You cannot find the VSA with the CMC, and cannot recall its IP address. 1. Close your CMC session. 2.
5 Designing a virtual SAN The HP P4000 VSA enables full featured use of the SAN/iQ software in a virtualized environment. When deployed correctly, HP StorageWorks P4000 virtual SANs are scalable, highly available, and fully redundant. Figure 7 Example of a virtual SAN using the VSA . Designing your virtual SAN The design of your virtual SAN affects both its performance and its reliability for production use.
• Reserved memory based on total disk capacity, as listed in Table 8 on page 28. Table 8 Memory requirements for VSA disks Total capacity of all installed disks Requires at least this much memory ESX Server • 500 GB • 384 MB • 500 GB to 4.5 TB • 1 GB • 4.5 TB to 9 TB • 2 GB • 9 TB to 10 TB • 3 GB Hyper-V • 500 GB up to, but less than 4.5 TB • 1 GB • 4.5 TB up to, but less than 9 TB • 2 GB • 9 TB up to, but less than 10 TB • 3 GB • A single virtual CPU with at least 4000 MHz reserved.
• Be configured to start automatically and first, and before any other virtual machines, when the ESX Server on which it resides is started. This ensures that the VSA is brought back online as soon as possible to automatically re-join its cluster. This is an installation option of the Hyper-V VSA. • Use redundant RAID for the underlying storage of a VSA in each server to prevent single disk failures from causing VSA system failure. Do not use RAID 0.
CPU Because the CPU of the VSA must be reserved, platforms that will host a VSA and other VMs should be built with more processor cores to accommodate the additional VMs. Multi-core processors with at least 2 GHz per core should be used so that a single core with at least 2 GHz can be reserved for the VSA. All additional cores are then available for use with other VMs, thereby avoiding resource contention with the virtual SAN.
Using VSAs with HP StorageWorks SAN Solutions VSAs and physical platforms can be mixed in management groups and clusters. When mixing virtual and physical platforms, and mixing differently configured VSAs, you should take the following requirements and guidelines into consideration. Cloning VSAs To clone a VSA, you must do so while the VSA is still in the Available Nodes pool, before you add it to a management group. Cloning a VSA after it is in a management group is not supported.
Create additional disks Create up to 4 additional disks for a VSA. Requirements • Minimum size - 5 GB • Maximum size - 2047 GB for ESX, 2040 GB for Hyper-V • Created sequentially as follows: • ESX Server—from SCSI 1:1 through SCSI 1:4. This assumes that the first disk has already been created and assigned to SCSI 1:0. • Hyper-V—Add up to four additional disks to SCSI Controller 0, location 1 through 4. This assumes that the first disk has already been created in SCSI Controller 0, location 0.
2. Select the Storage configuration category and select the Disk Setup tab. 3. Select the disk you want to add to RAID. Disks must be added to RAID sequentially. For example, you cannot add disk 3 to RAID if disk 2 has not been added. 4. Right-click and select Add Disk to RAID. Changing the disk size on the SAN Use the VI Client or Microsoft Hyper-V manager if you want to change the disk size of a VSA that is currently in your HP StorageWorks SAN Solution.
