Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Preface Audience and Assumptions The audience is assumed to be junior to mid/level system administrators who are not necessarily familiar with HP-UX. The user is: o Already trained on the usage of the Dell Compellent Storage or storage has already been allocated; this is not covered here. o Familiar with switch zoning or the zoning is already accomplished as this is not covered here.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Introduction This document presents useful information on a wide variety of HP-UX topics not covered in other Dell Compellent documentation. While this document contains significant detail, it is by no means a comprehensive or complete representation of every HP-UX method or function (nor is it intended to be). All of the procedures contained herein are handled more completely in HP documentation, which also includes the system MAN pages.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Best Practices Best practices in enterprise environments dictate the elimination of single points of failure in server installations; this includes all required resources: power, storage and networking. For purposes of this document, we are assuming that both networking and power are redundant and configured correctly.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Compellent Storage Center controller, LUNs are also mapped across the FC fabric in a redundant manner (i.e. one or more VLAN); although all mappings would tie into the single WWPN/WWNN of the single FC port on the HP-UX server.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Setup and Configuration HP-UX 11i v2 and v1 with Controller Failover Dell Compellent Storage Center employs two methods for high availability. Legacy Mode N_Port ID Virtualization (NPIV) For more in-depth information on these two modes, please refer to Dell Compellent Storage Center User Guide.

Dell Compellent Confidential disk Vol 30 1/4/0/0.206.5.255.0.0.0 HP-UX Best Practices 11i v2 and 11i v1 /dev/dsk/c29t0d0 /dev/rdsk/c29t0d0 sdisk CLAIMED DEVICE COMPELNTCompellent /dev/dsk/c30t0d0 /dev/rdsk/c30t0d0 As shown in RED above and for sake of this discussion, please assume that the device located at this address 1/4/0/0.206.2.255.0.0.0 is the primary path to the device /dev/dsk/c27t0d0. In order to determine the alternate path to this device, issue the command.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 To confirm that the alternate additional path to the LUN has been added to the Volume Group, issue the command.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Logical volume "/dev/vgdemo/lvol1" has been successfully extended. Volume Group configuration for /dev/vgdemo has been saved in /etc/lvmconf/vgdemo.conf To validate the Logical Volume creation, issue the following command.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Now issue the following command to mount this new filesystem. Type: mount /vgdemo Confirm that the newly created and mounted filesystem is ready for use with the command.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Dynamic LUN Expansion (DLE) and Dynamic LUN Contraction (DLC) This section builds upon the example used in the previous sections. Please also familiarize yourself with the HP documentation about the new “‘vgmodify” command before attempting this procedure on any production system. Using the vgmodify command to perform LVM Volume Group DLE and DLC http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01920387/c01920387.

If this LUN is already part of a Volume Group, you would now want to expose the additional capacity of the LUN to the Volume Group that it is a part of.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 mode. In any production environment, this would also require the necessary planning for downtime, as well as getting any necessary change management approvals. The first step in this process is to ensure that the Volume Group is OFFLINE (inactive) and if it is part of a cluster (MC/Serviceguard or otherwise), then also made cluster unaware; if PE/Renumbering is required, it would also need to be addressed accordingly.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 From this output above, we would want to identify the most optimized set of parameters based upon approximated LUN sizes, which would be added to this Volume Group. Since the initial LUN was 30GB in size (and since expanded to 50GB on the Dell Compellent Storage Center), and with the assumption that subsequent LUNs will max out around 250GB, we will use the parameter set identified in RED above.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 "/dev/rdsk/c27t0d1" size changed from 31457280 to 52428800kb An update to the Volume Group IS required New Volume Group settings: Max LV 255 Max PV 8 Max PE per PV 16380 PE Size (Mbytes) 16 VGRA Size (Kbytes) 1088 New Volume Group configuration for "vgdemo" has been saved in "/etc/lvmconf/vgdemo.conf" Old Volume Group configuration for "vgdemo" has been saved in "/etc/lvmconf/vgdemo.conf.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Dynamic LUN Contraction (DLC) and Thoughts With HP-UX 11i v2 (and the patch PHCO_35524 or later), the “vgmodify” command DOES NOT provide a “-C” parameter for the resizing of a PV (Physical Volume). Any LUN (PV), Logical Volume or Volume Group reduction effort will need to be performed in a completely OFFLINE mode.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Data Instant Replay (Continuous Snapshots) It is often required in an enterprise environment to freeze and capture the state of a data set at a specific point in time; there are many and various reasons that this is needed, including but not limited to data backups, configuration snapshots prior to system upgrades etc.

Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Type: vgchange –a n /dev/vgdemo Volume group "/dev/vgdemo" has been successfully changed. You would now capture the replay of this LUN on the Dell Compellent Storage Center (as will be discussed in the section below). When complete you would reenable I/O (writes) to the Volume Group with the command “vgchange –a y /dev/vgdemo”.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Back in the main Dell Compellent Storage Center window, you will notice a new button named “Replays” across the top button bar, left-Click to select it.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 You will notice that the replay just captured in highlighted in blue. The Dell Compellent Storage Center replays cannot directly be remounted back to its original or alternate host. You would need to create a new Volume/LUN from this replay and then map this new Volume/LUN to the intended host; right-Click on the replay and select the “Create Volume from Replay” option.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 In the next dialog, give the new Volume/LUN a new name. In this case we will accept the default name being “DanPreTest106 View 1”, then left-Click the “Create Now” button, then left-Click the “Quit” option when presented with the “Map Volume to Server” dialog. As you can see, the new Volume “DanPreTest 106 View 1” is now shown in the screenshot below in an unmapped state.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Mounting to the same host Prior to mapping this LUN to a host, capture the following output from the host STDOUT. Type: ioscan –kfnC disk disk disk 7 0/2/1/0/4/0.236.1.0.0.0.1 /dev/dsk/c11t0d1 12 0/2/1/0/4/1.236.9.0.0.0.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Since this new LUN shares the same Volume Group name and Volume Group Instance number as “vgdemo”; we will need to create a new Volume Group and change the Instance number on this LUN. Type: ls –la /dev/*/group | awk ‘{print $6}’ (This tells us that only VGID 0 and 1 are in use, we will create the next Volume Group with VGID 2).

Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 If importing to the same host, the vgchgid command needs to be applied to all volumes of the Volume Group at the same time. Type: vgchgid /dev/rdisk/disk147 /dev/rdisk/disk148 /dev/rdisk/disk149 /dev/rdisk/disk150 /dev/rdisk/disk156 The vgimport command would likewise need to be applied to all volumes of the Volume Group at the same time as well. Type: vgimport –m /tmp/vgdemoStripe8_import.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 host). The import of this Volume Group would then conclude with the appropriate vgchange, fsck, mkdir & mount commands accordingly.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Thin Provisioning The concept of Thin Provisioning (and space reclamation) is the means by which an OS and its chosen volume and file management platform interact with the Dell Compellent Storage Center products.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Tuning for Performance In order to achieve optimized I/O with any OS platform, the proper tuning/configuration of various kernel, SCSI, network and filesystem parameters may be required; the process of tuning in itself is not a science but an art of understanding the performance and various I/O requirements of the respective environment and application ecosystem that you manage.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Dynamic Root Disk The HP-UX DRD (Dynamic Root Disk) toolset is made available by HP for purposes ranging from production/patch lifecycle management to OS upgrades and actual and/or exercised disaster recovery events. This toolset has been named (as such) for its intent to work primarily with your root Volume Group (i.e. vg00 under LVM control). This toolset is available for HP-UX 11i v3 (LVM 2.x and 1.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 (Where the multiplication of the two values in RED would give you the size of the Volume Group, in this case 32 * 4346 = 139072 ie. 146GB excl. overhead). Having discovered the size of the vg00 Volume Group, we would now present a new LUN to the target host as shown below. For the sake of simplicity, we shall present a new 200GB LUN.
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 configuration snapshot of the system or as a backup copy of your vg00 Volume Group (where you might be installing a yet untested software package or patch set). Once created, this PITC may be brought back online as a mounted filesystem in cases where you might need to rollback certain files to previous known good versions. To create a PITC, issue the command.

Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 Boot from SAN (OS Boot Volume) To boot from SAN, you would need to configure the Dell Compellent Storage Center presented LUN as a bootable device path. We would achieve this with the command as follows. Type: /opt/drd/bin/drd activate OR Type: setboot –p 0/2/1/0/4/0.236.0.0.0.0.0 (Where –p: represents configuring the path as the primary boot device and where either of the dual paths may be used to identify the bootable device).
Dell Compellent Confidential HP-UX Best Practices 11i v2 and 11i v1 iSCSI and HP-UX iSCSI is an Internet Protocol (IP)-based storage networking standard for linking data storage facilities. By carrying SCSI commands over IP networks, iSCSI is used to facilitate data transfers over Intranets and to manage storage over long distances. iSCSI can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet and can enable location-independent data storage and retrieval.
