  1. why dynamic disk?
    just wondering

    • Satheshwaran Manoharan

      Dynamic disks offer greater flexibility for volume management because they use a database to track information about dynamic volumes on the disk and about other dynamic disks in the computer. Because each dynamic disk in a computer stores a replica of the dynamic disk database, for example, a corrupted dynamic disk database can repair one dynamic disk by using the database on another dynamic disk. The location of the database is determined by the partition style of the disk. On MBR partitions, the database is contained in the last 1 megabyte (MB) of the disk. On GPT partitions, the database is contained in a 1-MB reserved (hidden) partition.

  2. Dear Satheshwaran,
    I have a local disk c: which is a basic disk and 2 spanned volumes e: and f: respctvly.I am talinking about a scenario when I found the spanned volumes which are derived from the IBM storage, got unmounted and and I could nt see the disks in the diskmanagement.msc , NOW
    Q1. If i rescan the disk they are not visible, hence do i unmount it from the storage and remount?

    Q2 I f I remount the disk , what happens with the spanned volumes? DO I lose data?

    Q3 If yes , what is the best practice to do it?

    Thanks,
    Appreciate your patience and time

      Make sure its connected to the server. if you couldn’t connect it . try connecting with some other host and retrieve the data.
      I strongly feel. the host is not connected.

  3. I am trying to rigister an intiator for iscsi lun, if I select intiator type clariion/vnx, it didn’t allow me, the ok button has not activated unless I select cellera as intitaor type.
