The following describes procedures to execute Logical Device Expansion.
Procedure
1 Click [Logical Device Expansion] under the RAID Management in the
[Configuration] menu.
→ The [Logical Device Expansion (Initial)] screen appears.
• When Resource Domains are registered in the ETERNUS DX400/
DX8000 series, the RAID Groups for which LDE can be performed differ
depending on the current user account.
- When logged on using a Total Administrator account, LDE can be
performed for all the RAID Groups that are assigned to Resource
Domains.
- When logged on using a Resource Domain Administrator account,
LDE can be performed only for the RAID Groups that are assigned to
the relevant Resource Domain, and only for the RAID Groups that
are assigned to the Shared Resource.
When the capacity of the individual RAID group disk drives needs to be
increased, "RAID Migration" should be used instead of "LDE".
If there is at least one of the following, a messa g e t o t h a t e f f e c t i s
displayed, and LDE cannot be executed.
• When there is no RAID Group that LDE can be executed on.
• When there is a RAID Group where LDE has already been
running.
• When there is an abnormal component in the CE.
• When the device is operating in Write Through Mode.
