HP Integrity is a series of server computers produced by Hewlett Packard Enterprise formerly Hewlett-Packard sincebased on the Itanium processor.

Early Integrity servers were based on two closely related chipsets. If more slots than this are needed, two scalable memory adapters can be attached instead, allowing up to 48 memory slots. The successor chipsets were the zx2 and sx respectively. The 1U rx server is based on the zx1 chipset and has support for one or two 1.

The 2U rx server is based on the zx1 chipset and has support for one or two 1. The 2U rx server is based on the zx2 chipset and has support for one or two 1.

The 2U rx i2 server used the Intel Itanium series chipset with 8, 4 or 2 processor cores available. Among features common for the series: [3]. Both of these models come with integrated USB and video as default, which enables support for Microsoft Windows operating systems.

The rx is architecturally the same box as the rp, and can be changed from PA-RISC to Itanium 2 support with the flip of a switch. This design allows the servers to be divided into hardware partitionsor groups of cell boards. Each partition is able to perform as if it were a separate server.

The rx series are the smallest cell-based servers from HP. Just like the bigger rx see below and the HP Superdome see belowthese servers can be partitionedeither as one big partition two cells in one partition or as two independent cells. Just like the smaller rx see above and the HP Superdome see belowthe rx can be partitioned using any combination of the four available cell boards minimum of one, maximum of four separated partitions.

Cells can be freely moved from a rx series to a rx series as long as the chipset is the same on the cells, and the firmware is compatible.

It only takes a minute to sign up. Be aware that parity initialization only occurs when the controller is not busy. If you are actively using the controller, it will not be making much progress towards completing initialization.

To make initialization complete as fast as possible, allow the system to sit idle until initialization completes. If this setting is set to "Delay", then the controller will have to be idle for the specified number of seconds before it resumes a surface scan or parity initialization operation. Setting this to "High" should force the controller to make some sort of progress even if it is busy. After initialization completes, though, you'll probably want to reset this back to whatever value it started with.

The controller you have is older, but there have been a multitude of changes to the controller firmware since the version you're running on. You're at ROM revision 2. Also see this HP advisory indicating the same. You could install firmware piecemeal or just run a current HP Firmware DVD to bring the entire system, including disks, up-to-date.

A disk firmware updabe is available. It may resolve your issue "This firmware prevents a rare condition that may occur during a WRITE SAME command sequence that may result in incorrect data being written to the hard drive. Sign up to join this community.

My problem is that One week later the controller still was initializing parity. But, one week later working with high priority the "Parity Initialization Status" is still "In Progress".

Do you know if this is normal and I should let It continue working? Do you know any way to check if really "Parity initialization" is being done and how long It will last? Thank you very much. Javier Sanchez Javier Sanchez 21 1 1 gold badge 1 1 silver badge 2 2 bronze badges.

Looks like BBU is absent. When controller hasn't a battery it turn off write-caching that slowdown performance significantly. Active Oldest Votes. What do you mean by "let the system sit idle"?

Does this mean booted into the OS - just not using the server much? My array is still at 0. Kind of difficult to do for an OS disk isn't it? Should I find some way to pause the server before the OS loads? Firmware first! Other notes You may run into interoperability issues until you upgrade the controller firmware.The following criteria is being considered: Driver name Name of the Linux kernel module.

If the name changes between kernel versions, remember to include information in the detailed information section. Supported Supported by Linux kernel? Is the kernel driver needed for this RAID system available in the default kernel? Status RAID status easily available? If not, is the source for some command line tool available which can report this status?

Minimum status information is OK or degraded i. If such information is easily available, monitoring tools can be written to detect and report failures.

Is the source for a command line interface tool available for adding and removing disks from the RAID set? This is a must when maintaining a lot of machines using for instance a serial line console. Some find it easier to use graphical tools. Same source requirements as the CLI tools. Debian-Installer Is the hardware supported by the Debian-Installer? If not, please report a bug with workaround if known. Yes hpsa Yes Yes Yes?

Details about individual drivers 3w-xxxx Hardware using this driver: 3ware 8xxx controllers and earlier. There is a GUI tool 3dm2 accessible via browser used for management and monitoring daemon that configures the RAID, monitors the disk status and sends mail on failure. Also, afacli requires libraries that are no longer available in Debian distributions. At the end of aacraid section is the old information on tools available on Dell website, which may be useful for older distributions and controllers.

Below is information on the old afacli tool Dell also provides some admin tools in binary form. Latest version seems to be provided as afaapps The RPM can be converted to.

Debian kernel freezes rejected IO to offline devices in case array becomes downgraded ie one disk failed. The driver is in the main kernel as of 2. They have, amongst others, an 'archttp' module which enables a web interface! Archttp is statically linked so it will run in virtually all circumstances. Well, you really have to see it. CLI tool statically linked i and amd64 binaries also can be downloaded from ftp site. The 'sg' module must be loaded for it to work, the cli program segfaults without it.

A daemon detecting status changes and reporting to syslog as SNMP traps is packaged as cpqarrayd. The array-info tool can extract the RAID status for cciss devices.Turn on suggestions. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

FBWC is a flash based cache module that does not have the battery limitation of how long it can retain what is written to the module. You can find FBWC architecture via this whitepaper.

They have super capacitors to provide power to flash write cache memory. Occasional Visitor. If so, which one is faster?Are they the same or is there any performance penalties?

You can find FBWC architecture via this whitepaper. BBWC works as everybody knows. There is DRAM memory module which contents are retained as long as the battery has some juice left. FBWC, on the other hand, works differently. It also needs a power source to operate properly but with much smaller amount of energy thus enabling capacitors instead of batteries to be used. The crash event in case of FBWC use goes as follows:.

Super Capacitors wear off eventually but HP does not state how to diagnose them but opening the server and checking leds on the memory module. Are there any disadvantages for not using the capacitor pack? I read cache data could be stored about 1 year there. How about without it? I'm not sure what you are asking? You need the capacitor to power the copy from DRAM to the flash.

Occasional Visitor. The truth is not so simple. Two last things: 1. Because both caches use DRAM memory there is no performance difference there.

Greetings Stromberg. HPE Pro. I assume once it is on the flash, the capacitor isn't used. If you don't have a capacitor, you don't have a write cache.

Hewlett Packard Enterprise International.I like to use my hardware with zfs but since zfs has its own raid functionality I'd like to tell the raid controller to show the raw disks to my OS.

Only by removing the logical drives on the controller does not help. I thought there where a firmware bug somewhere so I have updated firmware in places I did not know had firmware bios, raidctrler, disk enclosure, psu? Go to Solution. Except the smartarray P and Pi inside an Integrity server the smartarrays cannot present "raw" disks, but logical drives only.

The RAID function cannot be disabled on the system you have. You can put each disk in its own array effectively creating many single RIAD 0 logical drives. However, the only workaround is creating a RAID0 on each disk, but in case of a disk swap you not only need to replace the disk, but also re-enable the destroyed RAId 0 on this disk, then adjust your software RAID.

It depends, but you can mirror a disk on controller A to a disk on another controller B this way to have more redundancy.

If you really want to do this, consider to create a RAID0 on each single drive. I prefer the hardware raids, because it is much easier to handle bad disks.
