• HP Envy 17 K2Z68AV: Adding a second hard drive for HP Envy 17 K2000 Series notebook PC

  So, I have been looking around for more information on adding a second HDD/SDD in my model of laptop computer on the web, but can't find anything on my specific model. Many places say K-series laptops have only one hard drive Bay, and that you use a hard drive caddy optical Bay. Moreover, I found videos of very similar models being dismantled, which seem to have only room for 1 hard drive. However, I was told to support twitter HP want all 17 have 2 hard drive slots. Can I get a confirmation, just to be sure?

  Hey @MrMdr,

  Thank you for visiting the HP Forums! A place where you can find solutions for your problems with the help of the community!
  
  I stumbled upon your post on the laptop and wanted to help you! I looked in your question about your Notebook HP ENVY - 17 t - k200 CTO, model #K2Z68AV and concerns with the second span. Looking to 256 GB SATA m2 (MLC) that could be used for storage only. It is a hard drive, but it fits differently than the main hard drive. Hereis a link to your manual page 2 which shows the specifications.

  It shows you how to install this on page 68 of the manual.

  Please let me know how it goes.

• New HP and adding a second hard drive

  Just bought a HP Pavilion HPE h8xt, will, adding a second drive, and once that happens, the warranty? The second hard disk will be the data from my old computer and serve storage.

  Hi TIF

  Who should not void the warranty unless you damage the hardware while making it... for not to spill a drink on your PC

  Here is a support document which should help you to install the second disk hard after PC arrives:

  I hope this helps.

• Data to be moved to the new storage array: ASM_POWER_LIMIT question

  DB version: 10.2.0.4
  Solaris operating system: 5.10
  Setup: 2 NŒUD RAC storage 2 TB of data in 4 LUNS (all 4 LUNs belong to a single storage group)
  
  We will replace our IBM 2 existing a new 4 TB storage array to Sun Storagetek.
  
  That's what I decided to do after a few R & D.
  
  Below are the steps that I've prepared based ML Note: 557348.1
  
  Create 4 LUNs on the new storage, and then create a test using Diskgroup
  

  SQL> CREATE DISKGROUP TEST EXTERNAL REDUNDANCY DISK '/rdsk/c0t1s1', '/rdsk/c0t1s2', '/rdsk/c0t1s3', '/rdsk/c0t1s4';

  Check if the diskgroup is created and mounted:

  SQL> SELECT STATE, NAME FROM V$ASM_DISKGROUP;

  If so, then manually mount on other instances of ASM:

  SQL> ALTER DISKGROUP TEST MOUNT;
  SQL> SELECT STATE, NAME FROM V$ASM_DISKGROUP;

  If the previous steps were successful and the diskgroup TEST can be mounted with success (on each ASM instance), and then drop the diskgroup TEST as follows:

  SQL> alter diskgroup test dismount; --(from all the ASM instances, except from one).
  
  SQL> DROP DISKGROUP TEST; --(from the ASM instance, which the diskgroup is still mounted). 

  Records of candidate is ready to be added to the desired diskgroup:

  SQL> ALTER DISKGROUP <my production diskgroup> ADD DISK '/rdsk/c0ts1', '/rdsk/c0t1s2', '/rdsk/c0t1s3', '/rdsk/c0t1s4';

  My question:
  Since involved LUNS are of large size, and rebalancing would make the command Add DRIVE slower. Right?
  I am thinking of setting the ASM_POWER_LIMIT to 0 until I started to do this and later new rever to 1. Is this a good approach?

  Hello

  My question:
  Since involved LUNS are of large size, and rebalancing would make the command Add DRIVE slower. Right?

  No, when you run the command ' add/drop disc' ASM reads and writes only metadata in the headers of all asmdisks (belonging to the diskgroup) and the guest is released.
  The complete rebalancing of the data process runs in the background.

  The fact that the guest to be released does not mean that the operation has ended. You need to check on the V$ ASM_DISKS (GROUP_NUMBER, PATH, HEADER_STATUS, NAME) to determine if you can remove the disks to the HOST.

  see this example (no difference at the time of change of power of rebalancing)

  ===================================================
  
  SQL> ALTER DISKGROUP DG_DATA
          ADD DISK '/dev/oracleasm/disks/ASM_VOL'
          DROP DISK DG_DATA_0000
  REBALANCE POWER 0; 
  
  Diskgroup altered.
  
  Elapsed: 00:00:07.90
  
  ====================================================
  SQL> ALTER DISKGROUP DG_DATA
          ADD DISK '/dev/oracleasm/disks/DISK01'
          DROP DISK DG_DATA_0001
  REBALANCE POWER 5; 
  
  Diskgroup altered.
  
  Elapsed: 00:00:08.21
  

  I am thinking of setting the ASM_POWER_LIMIT to 0 until I started to do this and later new rever to 1. Is this a good approach?

  You must know that the rebalancing will take place when there is a change of configuration diskgroup.
  Be careful, affecting the ASM_POWER_LIMIT 0 can let the diskgroup in a State of imbalance or unbalanced. (I do not recommend this)

  My recommendation:

  (* 1) save all your databases and valid backup (always required to protect your data). *

  You NEED to check the note below before add your ASMDISK.
  * Block Corruption in ASM while that balance [ID 1098453.1] *.

  2) run in two steps

  alter diskgroup  add disks  rebalance power x;
  alter diskgroup  drop disks  rebalance power x;
  

  Or Execute in a single step. (My favorite)
  Alternatively, we can run add disk & drop drive statements in a single operation, in what way that a rebalancing operation will be launched.

  alter diskgroup 
   add disk 
   drop disk 
  rebalance power 9;
  

  Wait until the end of the operation of rebalancing.
  You can follow the process of rebalancing using the following queries:

  SELECT  NAME,
       PATH,
       HEADER_STATUS,
       ROUND(TOTAL_MB/1024)  TOTAL_GB,
        ROUND( FREE_MB/1024) FREE_GB,
       ROUND((TOTAL_MB-FREE_MB)/1024) TOTAL_USED_GB
  FROM V$ASM_DISK
  WHERE GROUP_NUMBER= (SELECT GROUP_NUMBER FROM
       V$ASM_DISKGROUP WHERE NAME='DG_DATA');
  
  select * from v$asm_operation; 
  
  select * from gv$asm_operation;
  
  select      NAME,
       ROUND(TOTAL_MB/1024)  TOTAL_GB,
       ROUND( FREE_MB/1024) FREE_GB,
       ROUND((TOTAL_MB-FREE_MB)/1024) TOTAL_USED_GB,
       UNBALANCED
  FROM V$ASM_DISKGROUP;

• Satellite P300-16 t - adding a second drive HARD-success!

  I have added a second hard drive today for my Toshiba P300-16 t.

  I realized that I had a Toshiba SATA drive in a USB disk device that would spare - 250 gb.

  I improvised by removing the feet spread on the cover of the second cage to hard disk using a sharp knife. I put the Bank in place ensuring maximum safety. I also used a heat-resistant material (say what) to secure the drive up as readers are rarer than hen's teeth. I made sure that the reader also had room to breathe. The cover was then released and I turned on my computer and it found the new HDD, the installed drivers at home but hey presto! Another 250 GB to play with.

  Now, I did it is because I call four FSA in the United Kingdom but they weren't any help by providing a cage for the second disc.
  Two said they only deal with businesses and not individuals.
  Others have said that they only provide power cables and batteries!
  Hope that my Tosh never goes down and I must use their services...

  Anyway, I don't recommend anyone do what I just - it is possible if you are a bit adventurous...

  Have you used the Hotglue?

  Surely, you can get the FSA HARD drive media. Unless there is a global shortage on cradles P300: p

• ATER ADDING A SECOND HARDRIVE MY COMPUTER IS NOT ALLOWING ME to SAVE music to what HE SAID I'm not administrator that he

  Recently, I added a second hard drive and now although I can access my files from the original hard drive, it doesn't let me download files outside such as CD as it says I need to "contact the administrator"! Can you please help me solve this problem? Thank you.

  Hi Paul,.

  In Microsoft Windows XP, the special access permissions are customizable sets of permissions. This means that you can apply special access permissions to files or folders that are located on NTFS file system volumes. This article describes how to set, view, change, or remove special permissions for files and folders.

  Method 1: To take possession of the drive in disk management:

  a. click the Start button,

  b. Select Control Panel,

  c. click Administrative Tools then computer management

  d. open disk management.

  Method 2: Change the drive letter:

  a. click on Start

  b. Select Control Panel

  c. open Administrative Tools

  d. Select computer management

  d. select disk management in the section at the bottom left. You can change the drive letters on the right.

• Adding a second controller - 3750 G integrated WLC

  Hello all-

  I am new to this, please bear with me.

  I was responsible for adding a second WLC in the customer's network. They currently have a 47 access support 4402-50 points. The customer has purchased a 3750G w / integrated WLC (50AP) anticipate the addition of several APs, but the Bill is pending. In the meantime, the le client customer wants the WLC new to help balance the load of the AP. The existing WLC is running 6.0.182.0. The customer has a mixture of APs 1130, 1140, 1240 and 1250. They begin to use the features of N.

  The two controllers are now on the same subnet. 10.1.113.x I've updated the code on the 3750G_WLC to match the other controller. Here are some questions I have now:

  1. am I correct in thinking that I should set these two controllers in the same group of mobility?

  2. am I right in thinking I have to manually configure each access point to point to the controller, I want that he be associated? In other words, is there a function for AUTOMATIC load balancing? (NOTE: the customer just bought and install WCS)

  3. once exceed US 50 APs, any other configuration change will have to happen?

  It's all a bit sketchy for me because we are right on the edge. Then. at the moment we are N + 1 request to balance between the two. Once exceed US 50 APs, we are no longer N + 1 and must elect which APs are a priority in case of failover.

  Some advice on the installation of this second WLC, in the network and any recommendations you may have to manage these 47 existing APs is appreciated.

  See you soon-

  Thus, when you set a primary controller and secondary, you specify the name of the controller. 5.2 and above you can also specify the IP address of the management of this controller. The AP will learn about these controller through mobility group set on the controllers.

  Lose the controller, I didn't set the priority after the fact. I meant that if you try to set priority (for the event that a controller has been lost), then you would create the priority on high tab override the configuration of the AP. When you first install, you would like this.

  If you don't set a primary/secondary, the AP should know the controllers of each controller, and when the controller sends its replies of discovery, it must specify only one to balance the load of. Or something like that.

  The bottom line, is that if you do not have a primary/secondary set, then the AP discovery process should get your AP on the less busy controller. It is the primary/secondary definitions which kind of replace it, which is what I called a "manual"... balancing

• Adding a second hard drive internal

  I use an old HP Media Center PC m700, product: m7041. I have tried adding a second internal hard drive, but unfortunately do not know how to start. Could someone help me please?

  I'll start by guessing that you have a m7041.uk, given that your model number is incomplete. After you have a HP m7041.uk, you have the following types of drive Bay and the quantities;

  5.25 inches (CD/DVD), external x two (one available)
  a (busy) x internal 3.5-inch (hard drive),
  Personal Media Drive (available) x

  Because you don't have that a single Bay 3.5 "for a hard drive and it is already occupied, you will need to use the Bay 5.25" opened with an adapter like THIS or THAT. Please see these tutorials for HP on 'Adding or replacing a hard drive' and 'Adding or replacing a CD or DVD disc' to learn where and how to install the second hard drive.
