LVM disk power management

Hi,
I have 3 physical disks forming one volume group, with one logical volume.
If i try to issue a standby command to the logical volume..
sudo hdparm -y /dev/mapper/VG0-LVstorage
/dev/mapper/VG0-LVstorage:
issuing standby command
HDIO_DRIVE_CMD(standby) failed: Inappropriate ioctl for device
But if i issue a standby command to the individual disks in the volume group..
sudo hdparm -y /dev/sda1 /dev/sdb1 /dev/sdc1
/dev/sda1:
issuing standby command
/dev/sdb1:
issuing standby command
/dev/sdc1:
issuing standby command
This works fine!
Is this the normal way to to spin down the disks in a lvm volume group or will this cause file corruption.
And if not can anybody suggest a safe way to achieve this or is it just not possible to spin down disks in a lvm.
Kind regards,
Drew

Only physical devices are valid targets for hdparm, so the error you got running it on an LV makes sense.
As for the safety of spinning down disks in an active LV... if I were you I'd ask on the LVM mailing list. Though, if you're using three disks for one LV, I think you'd be better off with mdadm and a RAID providing some redundancy.

Power Management for HDD's and screensaver

Hi all
Here some specs of my 'old' trusty sys:
Intel 2.26GHz
1GB DDR
Gfx nVidia V6200
1xATA(Seagate) + 4xSATA(Maxtor's) HDD's in the range of 200-300GB each
Samsung SyncMaster 930BF
LiteOn and NEC DVD/CD reader/writers
The HDD's brings me to a little question, in the past (before ArchLinux) i've used to have power managment to put the 4 SATA HDD's (S.M.A.R.T supported) to sleep after 10 or 15 minutes inactivity or so. Is there something similar for ArchLinux? A GUI for Xfce4 for that kind of power management would be cool but is not nescessary.
And I was thinking of a cool screensaver, any sugestions?
I thank you'll in advance for any suggestions and advices.

As for the screensaver, the GLMatrix screensaver is pretty nice if you have direct rendering working.
I think you can use hdparm to enable hard disk power management. It is a CLI-only tool, but why not use CLI? Tbh, it is much easier for me to do configuration stuff in CLI rather than use a GUI for it.

D20 sata disk support advanced power management

My d20 comes with a sata 250 GB WD (WD2500AAJS). I have centos 6 on it now. hiberate seems not working on this box: 1. after hibernate it automatically power up but boot into a black screen with backlight on.
2. pm-suspend.log shows that everything is successful during hibernate stage, except that /usr/lib64/pm-utils/sleep.d/99hd-apm-restore.hook hibernate hibernate: Advanced Power Management not supported by device sda. (the WD disk is the only disk plugged into the system for debugging purpose)
3. hdparm -i /dev/sda returns AdvancedPM = no
My first step is to work on the hiberate/restore problem (leaving auto reboot later). So the problem and log/hdparm messages are consistent that the sata disk does not support apm. how to turn on the apm support? is there any specific option to specify in the BIOS? is there any bit to flip on the hard disk? ... (right now BIOS enables AHCI mode and in native IDE mode, disk connects through Marvell controller)
Thank you very much.

Hi, psuturtle:
Thank you for quick reply. This is the least I want to hear. It seems much on my own.
Googled around found a couple of related topic:
1. http://wdc.custhelp.com/app/answers/detail/a_id/958/~/how-to-enable-and-disable-pm2-%28power-managem...
Basically, WD sata disk is by default disabled with its APM. It instructs to "place a jumper shut on pins 3 and 4", though I haven't tested it. I don't know how windows circumvent this hd option problem though. On the other hand, if the disk is connected to one of the 3 IDE connectors (for optical drives), suspend/hiberate works fine although having slow I/O after resume (I did this with Fedora 14/15 but haven't tried on centos). So I guess it is Marvell Constroller drive might have some unexpected effort here.
Well, thank you anyway.

Power Manager locking taskbar and creating two battery icons on X201

I am having an issue with one of my X201s and Power Manager running windows 7. My other X201 that runs the same software and was buil7 withing a few months does not have the issue. Periodically while on the internet a second battery icon will pop up on the task bar just partially overlapping the first icon and it has a fluttering appearance. When that happens the task bar is frozen and it takes accessing task manager to be able to restart the computer. I uninstalled and reinstalled the latest versions of the driver for Power Manager and Power Manager but that did not fix the problem. Not running Power Manager seems to prevent any problems but that is not what I want to do. I did some reading last night and it seems I am not the only one having an issue and it is not confined to the particular model. Searching did not lead me to real answers. Looking for a solution or a better way to diagnosis this.
T430 - Taskbar Frozen? This worked for me.
‎01-11-2014 01:44 AM
I thought I would post this in case someone has the same issue I did. Today my taskbar froze after startup (i.e. I couldn't access the start button or any other icon on the task bar and I had a two wonky grey battery icons where only one should have been). Restarting explorer.exe didn't help. It didn't even work in safe mode. No viruses, malware, disk/hardware issues could be found. The culprit was the Power Manager. There have already been a couple threads on this, but they are somewhat convoluted in addressing the issue so I thought I would post a straight forward solution.
I had version 6.3x installed on my T430 (which is only a couple months old, by the way). I had read in another thread that the power manager has been causing problems with the taskbar from way back BUT merely uninstalling it after the problem occurs has triggered the blue screen of death for several users.
So, I downloaded and installed the latest version of Power Manager (currently 6.6x). I did not uninstall the previous version first. I simply installed the new version and restarted the computer when prompted. This fixed the frozen taskbar issue.
Then, and only then, did I uninstall power manger completely because I never want to deal with this again. Everything is now back to normal.
The TL;DR version:
Step 1: Download and install latest version of power manager. DO NOT uninstall previous of power manager first.
Step 2: Restart computer
Step 3: For peace of mind, unistall the latest version of power manager.
Step 4: Restart computer
I hope this helps anyone who needs it.

Well using the older version of powermanger did not work as the issue popped up again. I also discovered the other X201 in the house was also having the same issue with the two battery icons and locked task bar.
I tried a new tactic which unchecking the the box in Power Manager-Options-Show periodic messages about the battery condition. This so far no brought up the problem but more testing is necessary to be certain.

I have an iMac G4 PowerPC with OS 10.5.? The OS10.5.8 update failed. Now get blue screen and error-can't find Intel Power Manager. What now??

I have an iMac G4 PowerPC with OS 10.5.? After deleting 17G of music files to make room on the 74G drive, The iPhoto and iWeb updates seemed to load okay, but the OS 10.5.8 update failed - message opened said the computer encountered an error and must shut down. Now I get the blue screen. Startup with 'V' pressed shows multiple lines saying: error-can't find IntelCPU Power Manager. What now?? I reset PRAM, I think.....?????

I am concerned that you might have applied a system updated intended for an Intel iMac, while you have a PPC (non-Intel) iMac. Your PPC OS should not be looking for an "IntelCPU Power Manager."
Have you tried booting from the 10.5 install DVD/CD and repairing the hard drive, plus repairing permissions?
If you done the repairs mentioned above, and your problem still persists, you can also try doing a safe boot. (see http://support.apple.com/kb/HT1455 ) Then, if none of these things worked, if I were in your shoes (it's hard to diagnose these things without being there in person) I would first check that there is adequate disk space, then I would boot from the 10.5 DVD/CD install disk and reinstall the operating system. There is an option to do an archive and install preserving user files/settings, that would be the option you want, as it will save your files but install a new OS. Make sure you have a good backup of your files first. If you do not have one, use "target mode" to copy all your files before embarking on an new OS install. Assuming that you do succeed with this install, then use Software Update to get the right updates for your iMac.

BSOD on boot due to Lenovo Power Manager

I was uninstalling this Power Manager last time on computer. I do not remember what version it was. It was stuck at 94% for long time (half hour), so I shutdown my computer instead of waiting for it.
Now my windows 7 cannot boot at all. Not even safe mode. All I can boot in is the repair tools, but the repair tools did not help at all. I cannot afford to reinstall a system as there r many important files inside C drive and user directory.
Blue screen says: Stop 0x000007B
I cannot believe this application is even more painful than removing a virus on the computer.
Waiting online for solutions as I really need my computer.
Solved!
Go to Solution.

First of all, thank you for replying such old and helpless topic. unfortunately I did not find a way to solve this issue. I highly suspect that is caused by one of sys file that power manger was using. I do not know which one. As a result I have to insert my disk to another computer retrieve all important files then do a reinstall. After reinstall everything works fine.
I am not gonna reinstall power manager again. It was a big disappointment from Lenovo.

Power Mac G5 DP1.8GHz - Bad Logic Board or Power Management Issue?

I have a Power Mac G5 DP1.8GHz/1.5GB/80GB which I bought non-working. It has not yet been disassembled or examined by a certified tech. This is it's issue (which replicates): the computer powers on. It makes a single warning tone, then the LED flashed at least 15 times (too fast to count). Then the posting chord is heard. Hard drive spins up. Then nothing (no video). Won’t boot from any disk. I have changed the RAM and tested the RAM banks with known-to-be-good RAM from another DP1.8GHz G5. The warning tone stopped once or twice after this switch, but then it didn’t chime. I changed the PRAM battery, but not with as new one. However, after installing the used one and then resetting the PMU, it displayed video briefly for the first time. While installed in the other 1.8GHz G5, the hard drive was formatted, given a clean install of OS X 10.4.11, and then moved into this computer where is never mounts. The computer is not accessible through TDM.
Do I have a bad logic board? Bad CPUs? A power managment issue? A RAM issue?

Through my own trial and error troubleshooting, I have found the CPUs to be in good working order and the logic board passes the Apple Service Diagnostic every time. Despite the installation of numerous pairs of modules that worked in another DP1.8GHz, the computer has a RAM issue-it gives the "no good RAM" tone most of the time when it powers up (after a PMU reset it does not). Also the computer boots from disk or into Open Firmware but the disk utility can't see either hard drive so I may have a bad SATA controller.

Where can I find XP x64 drivers for Portege R500 - hotkey / power management?

Where can I find downloads that will enable power management or hotkey support for my Portege R500?
I have already installed drivers for everything except fingerprint reader (don't want), tpm (really don't want), and hdd motion sensor (tos620a) (not bothered about right now). Most drivers are latest from original vendor websites, or, failing those, from Toshiba's Vista 64-bit download areas.
Everything else generally works: wifi, graphics & chipset, sound, lan, bluetooth stack, cardbus, card reader, etc.
However, having done this, the following issues remain:
FN hotkeys don't work for suspend to ram, suspend to disk, *screen* *brightness* - essential to extending lifetime; FN hotkeys for numeric/direction pad, external monitor toggle *do* work
Dedicated backlight toggle button doesn't do anything
However, in order to get battery lifetime beyond ~2.5 hours and closer to the rated 7.1 hours, I'll need to turn some things down / off occasionally. What software can help and where can I get it, such that it works on Windows XP x64 edition?
Note:
I have tried the xp 32-bit packages that Toshiba supplies, they don't appear to work on x64. The 'ctrls' package requires 'cmod', but 'cmod' gives this error:
TOSHIBA Common Modules Setup
Not an ACPI machine. Cannot install TOSHIBA ACPI Logical Device.
OK
I have tried the xp 32-bit package called 'pwrsav'; it installs a bad help link to my start menu, and adds a couple of exes, tpsmain and tpsoddctl, to my auto-runs. These 32-bit executables quit immediately after execution.
I would have tried to install Toshiba's Vista 64-bit packages for hotkeys / common modules / power management, but the only one of the three I can find via toshiba.co.uk are common modules, and unfortunately that zip file only contains .inf, .cat and .sys files, no installer.
Motivation:
I'm using a fresh install both because the default Vista install is unusable (900MB memory used on a fresh boot desktop, drive split into multiple partitions, trial, adware and broken software installed left and right)
I'm using x64 because I'm a software engineer whose next product needs to work on x64, and this new laptop was a likely first candidate

You didn't link to the tool you found. If you meant this tool then, you should be aware it doesn't work on x64 on R500:
Display Tuner
Cannot detect monitor!
Your monitor does not support DDC control or your videocard is not supported by Display Tuner.
You cannot use Display Tuner in this configuration.
OK
It would be unlikely to work in any case, as display driver brightness isn't normally the same as the screen's brightness (hence power usage).
Maybe it's a communication issue, but I *have* found +original+ drivers for all essential components, just not for things like screen brightness - something that, to be honest, I more expect to be handled in firmware / bios, as that's been my experience on previous laptops, and is more reliable in any case, considering I could be running an oddball Linux or a completely different OS, or a CPU-intensive high-priority task.
The R500 series seem to be scrimping on the firmware and expecting OS utilities and dedicate yet another system tray icon to take over that job.
It does look like x64 is a no-go for mobile use on this machine, due to lack of firmware power management, which is a great pity as the point of such a light machine is mobility. I'll wipe it and install XP 32-bit and see how that goes.

How do I TURN OFF power management???

My computer still keeps going to sleep and the only way to wake it up is to hit the reset button. I tried enabling the keyboard-wake-up to wake it up, but then it started rebooting itself spontaneously every 15 minutes -- without any warning from Windows. It doesn't matter whether I select S1/POS or S3/STR mode -- it does the same thing every time. I don't want S1 or S3 power management. I want to TURN OFF POWER MANAGEMENT COMPLETELY! I only want Windows to turn off the monitor. The BIOS should do nothing!
How do I accomplish this??????????
BIOS v1.3
NEO2-LS
Quickboot - disabled
IDE Busmaster - disabled
ATA mode - native
ATA config - P-ATA only
Performance mode - slow
dynamic overclocking - disabled
S.M.A.R.T. for hd enabled
Power Supply - @Power EP43057 (430W)
HD Western Digital UATA WD800JB
video card - MSI FX5600TD128
512MB Elixir 400 MHz DDR Ram
Lite-On DVDROM
Pentium 4 2.6GHz HT 800MHz

This is strange - my understanding is you would usually use the Power button to wake the suspended PC...
Could what you are experiencing be more of a shutdown or instability?
Is it due to BIOS setting or Windows? Here are some possibilities
1. What is your selected Power Scheme? Are your options for Turn off hard disks, System standby & System hibernates set to Never?
2. These BIOS settings work fine for me ...
ACPI Standby State : Auto
Power Management/APM : Enabled
Suspend Time Out : Disabled
Set Monitor Events
FDC/LPT/COM Ports : Monitor
Primary Master IDE : Monitor
Primary Slave IDE : Ignore
Secondary Master IDE : Ignore
Secondary Slave IDE : Ignore
Set WakeUp Events
Resume on PME : Disabled
Resume on RTC Alarm : Disabled
Keyboard PowerOn Function : Disabled
Mouse PowerOn Function : Disabled
3. Does your keyboard have any of those quick buttons for Power / Sleep / Wake ? Could any of them be stuck? (Mine has these in a most inconvenient place - between Delete/End/PgDn and arrow keys, so I sometimes accidentally pressed them)

Linux LVM (Logical Volume Manager) for CentOS on Azure?

Hi. I am trying out Azure and installed a OpenLogic CentOS 6 virtual machine. I note that it is not running LVM (Logical Volume Manager) by default. I would like to ask if it is possible to:
1. have CentOS Linux installed with LVM by default when creating a Linux virtual machine on Azure
2. switch to LVM after adding a new disk
On the other hand, is it a good idea to use LVM at all? Will it affect performance, features on Azure?
Thanks.

Hi,
Based on my experience, you can add disk to an Azure VM. You can install the Logical Volume Manager to manage the disks attached to the VM. In addition, there is no Linux VM with LVM installed by default. If you want to have this, please submit your requirement
in Azure feedback:
http://feedback.azure.com/forums/34192--general-feedback
In addition, since you can have only one OS system disk for an Azure VM, this limitation may make multi-disk logical volume manager setups unworkable.

Susie

Can't disable auto screen brightness on M92z even after using power manager

I find the auto screen brightness annoying and have been trying to disable it. When I go into power manager and turn off "auto" it works, but once I reboot, it's back on again.
I've gone into the sensor section of power manager and disabled the sensor but that too does not stick. I've also checked that "magic brightness" setting as well. Nothing seems to stick after a reboot. Things work until I reboot.
I have installed the latest power manager, but 2 things seem strange. website says latest version is 3.40.0002 but when download and install that version it reports 3.40.0001 (notice the 1 vs the 2). Also in control panel it says power manager 32 bit but my OS is Windows 7 64 bit.
Roveer

Alright, so this is ridiculous. Back to square one with nothing booting. I managed to get it booted up once fully, and another time booted off the OS10.3 disc (froze during disk repair in Disk Utility).
I don't have another hard drive to try, and I've taken it apart and reset everything.
Any ideas?

T61, WinXP SP2: Windows Power Options vs Thinkpad Power Manager (Standby/LID/etc)

My message is similar to this one:
http://forum.lenovo.com/lnv/board/message?board.id=T_Series_Thinkpads&message.id=4885
but show clear source of problem.
So I start...
I have [brand new ] T61 with XP SP2 Russian, installed from R&R disks from Lenovo through Vista Downgrade deal.
1. I set Windows Power Management (W.P.M.) to:
- standby when closing lid
- asks for password after wake up from Anabiosis (standby or hibernate).
2. Close lid -- notebook go to standby; open lid -- notebook wakes up. Fine.
3. Close lid -- nothing to do. Open lid - notebook runned a usual, no standby preparations ;(
4. Go to ThinkPad Power Manager (TP.P.M.) (useful left-click from Big Green Gauge in taskbar) -- all settings looks fine: options, checkboxes etc.
5. Open W.P.M. -- all settings messed up with random values:
- "no action" on closing lid
- "asks for password" checkbox not checked (this field varies through few tests).
6. Setting up needed options in W.P.M. again, repeat steps 2..3..4 -- nothing changes: W.P.M. saves options for first close lid action, then options messed up.
==================================
As I see, ThinkPad Power Manager builds on top of Windows Power Management and overwrites its options on some actions (power up/power down/close lid/etc) in unsmart way, turn off close lid action and bring *potentially security breach* by resetting option for asking password.
==================================
My other experience on close/open lid:
- Very old R43 at my work acts fine. TP.P.M. installed.
- HP 6820s works fine with standard W.P.M.
- HP nx7010 works fine with standard W.P.M.
Software versions:
- ThinkPad Power Management Driver: 1.44
- ThinkPad Power Manager: 1.30b
- All the hotfixes listed in similar topics installed by R&R disks
==================================
I... am... VERY... DISAPPOINTED! (c) Jean-Baptiste Emanuel Zorg
Is there a way to fix this TP Power Management suite behaviour?
Should I reinstall some of components?
Can I throw out TP Power Management toys and use WinXP native Power Management, ot there will be some ghosts like "yellow undrivered question marks" in Device Manager?
Thank you.

Message Edited by andyP on 04-22-2008 09:37 AM

I solved this trouble without Lenovo intervention:
- create clean WinXP Pro setup disk from R&R recovery diskset and install WinXP from it;
- install all the TP utilities & drivers manually, checking LID Close/LID open actions twice after each program;
- make full system backup (not R&R way) every 3..4 installed programs.
Entire process spend one week of my time.

Power Management blues...

I have a T61p running Vista Home Premium and recently noticed that Windows Update has been trying to install a driver every single day for the last 6 days and it always fails to install. It reads like this:
"Lenovo - Other hardware - ThinkPad PM Device
Type: Recommended.
Published: 8/25/2008."
But I wonder why Windows keeps trying to update a piece of software about which Windows itself reports the following:
"Update Drive Software - ThinkPad PM Device: The best driver software for your device is already installed. Windows has determined the driver software for your device is up to date."
What am I missing?
A check with PC Doctor for Windows detects a "Misconfigured" Power Management Driver and adds that this driver is either not installed or installed incorrectly.
Meanwhile, I completely uninstalled the seemingly faulty driver and all its components. However, when I check the list under Device Manager, the "ThinkPad Power Management" file remains listed. And when I check under "C:\DRIVERS\VISTA\x64" I find these three files:
"ibmpmdrv.sys"
"ibmpmsvc.exe"
"TpInsPM.dll"
Also under "C:\DRIVERS\VISTA\x86" I find those exact three filenames with exactly the same details.
I feel like I may be roaming around the beast but can't see it... Just the fact that these same 3 files are kept under two different folders under the VISTA common puzzles me. (And do those folder names "x64" and "x86" actually have any meaning?)
Can anyone help me try to make some sense of all this?Any help will be appreciated.
Thanks.

You might install istat from http://www.islayer.com/apps/istatpro/ to see what your actual temps are. Either there is not enough airflow and the system is overheating or there could be a sensor failure.
Ensure the air vents at the base are clear. One person's were clogged with cat hair because the cat slept next to the mini.
You can run the Apple hardware test to see if there is a problem with a sensor. Find your original OS X disks that came with the system, insert the disk that says 'AHT Version x.x' in small print on the label, reboot holding the alt/option key down, choose the Apple hardware test, and when prompted choose the extended test.

Software Issue with New Power Management Update

In this post I'll be talking about the Power Management update for Windows 8.1 Pro, version 1.67.09.00, released on 10/15/2014.
I installed this via System Update yesterday and, when shutting down my computer before going to classes that day, I noticed something odd. Even after Windows shut down, the display went black, and the hard disk indicator light (yes, please bring those indicator lights back to the Thinkpad line!) stopped flashing, the power indicator was still on. From there I deduced the system was still on in a "limbo" state. In fact, the keyboard light was still functional, and so was the mute button! I was right.
Later that day, I let my computer sit through this "limbo" state, and a horrible apparition, the Blue Screen of Death, appeared! It stated that there was a "Power Driver State Failure" and immediately proceeded to shut down my computer. I rebooted, used System Restore to undo the installation, and the issue was fixed.
In short, don't install this update if you have Windows 8.1 Pro and a Thinkpad X230 Tablet. It didn't work well for me. Lenovo, please double and triple check your update before an eager geek like myself proceeds to install it.
