Symptom

Two
pay-per-use ECSs run the same OS, for example, both run Windows or
Linux. The system disks attached to the two stopped ECSs are exchanged.
After the exchanging, the login passwords or keys of the ECSs may
change. In such a case, how can I log in to the ECSs?

support-doc-new-note.svgNOTE:

Before
stopping an ECS for disk detachment, release the IP address assigned to
the ECS using DHCP so that ECS can correctly obtain an IP address
later. To do so, perform the following operations:

  1. Log in to the Windows ECS.

  2. Run the following command to release the IP address:

    ipconfig /release

    This operation will interrupt
    network connections and affect the use of the ECS. After the ECS is
    restarted, network connections will automatically recover.

Windows

Login
methods vary according to the login authentication used on the ECSs.
For example, there are three Windows ECSs with parameters configured in Table 1.

Table 1 Parameter configurations

ECS

System Disk

Login Authentication

Password/Key Pair

ecs_01

vol_01

Password or key pair

If a password is used for login authentication, take Ecs@01 as an example.

If a key pair is used for login authentication, take private key file Keypair_01 as an example.

ecs_02

vol_02

Password

Ecs@02

ecs_03

vol_03

Key pair

Keypair_03

  • Scenario
    1: System disk vol_01 is detached from ecs_01 offline and then attached
    to ecs_02 as the system disk. How can I log in to ecs_02?

    After ecs_02 starts up, use its initial password Ecs@02 to log in to the ECS.

  • Scenario 2: System disk
    vol_01 is detached from ecs_01 offline and then attached to ecs_03 as
    the system disk. How can I log in to ecs_03?

    The random password for logging in to ecs_03 must be resolved again. The procedure is as follows:
  1. Locate the row containing ecs_03, click More in the Operation column, and select Get Password from the drop-down list.

  2. Click Select File and upload private key file Keypair_03 of ecs_03.

  3. Click Get Password to obtain a new random password.

  1. Delete the initial password for logging in to ecs_03.

    Locate the row containing ecs_03, click More in the Operation column, and select Delete Password from the drop-down list. Then, click OK.

    support-doc-new-note.svgNOTE:

    ecs_03 must be in Stopped state.

  2. Start ecs_03.

    Locate the row containing ecs_03, click More in the Operation column, and select Start from the drop-down list. Then, in the Start ECS dialog box, click OK.

  3. Obtain the password for logging in to ecs_03.

  4. Use the random password obtained in step 3 to log in to ecs_03 with the system disk replaced.

Linux

Login
methods vary according to the login authentication used on the ECSs.
For example, there are three Linux ECSs with parameters configured in Table 1.

  • Scenario
    1: System disk vol_01 is detached from ecs_01 offline and then attached
    to ecs_02 as the system disk. How can I log in to ecs_02?

    Use either of the following methods to log in to ecs_02:

    • Use private key file Keypair_01 (if available) of ecs_01.

    • Use the original password Ecs@02 of ecs_02.

  • Scenario 2: System disk
    vol_01 is detached from ecs_01 offline and then attached to ecs_03 as
    the system disk. How can I log in to ecs_03?

    Use one of the following methods to log in to ecs_03:

    • Use the password Ecs@01 (if available) of ecs_01.

    • Use private key file Keypair_01 (if available) of ecs_01.

    • Use private key file Keypair_03 of ecs_03.
