Dell PERC S130 - Virtual Disk Migration; Expanding Virtual Disk Capacity

Table 3. Read, Write, and Cache Policy for the PERC S130
Category Supported by S130 controller
Cache Settings Yes
Read Ahead/Write Back Yes
No Read Ahead/Write Back Yes
Read Ahead/Write Through Yes
No Read Ahead/Write Through Yes
NOTE: The current default for Write-Cache mode enablement is Write Through, No Read Ahead (WT, NRA). To enable
Write Back (WB), a UPS is recommended.
NOTE: For more information about the physical disk write cache policy behavior, see the Troubleshooting your system
section.
Virtual disk migration
The PERC S130 supports automatic virtual disk migration from one PERC S130 to another.
CAUTION: The virtual disk is lost if you perform a virtual disk migration during an Online Capacity Expansion (OCE)/
Recongure.
NOTE: Backup the virtual disk data before migrating virtual disks.
NOTE: Ensure that all physical disks that are part of the virtual disk, are migrated. Virtual disks in optimal and degraded
state are automatically migrated. A virtual disk in an oine state should not be migrated.
NOTE: A bootable virtual disk cannot be migrated between dissimilar system models.
NOTE: When you migrate virtual disks, ensure that you verify the number of virtual disks do not exceed 10.
Migrating a virtual disk
1. Turn-o the system that contains the source controller.
2. Turn-o the target system if the system does not support hot-insert of physical disks.
3. Move the appropriate physical disks from the source controller to the target controller in the target system.
Physical disks do not have to be inserted into the same slots in the target system.
4. If the target system was turned-o, turn-on the system.
CAUTION: The BIOS Conguration Utility (<CTRL><R>) pauses, and prompts for action, for the degraded virtual disk(s),
if the "pause if degraded" option is enabled in the BIOS Conguration Utility (<CTRL><R>).
CAUTION: After the migration occurs, ensure that all of the physical disks have been migrated and are present in the
appropriate virtual disks.
Expanding virtual disk capacity
The capacity of a virtual disk can be expanded online by using the Online Capacity Expansion/Recongure (OCE/Recongure).
OCE/Recongure is a process that allows you to add storage capacity to an existing virtual disk. In most cases additional storage
capacity can be added without taking the system oine.
NOTE: If an additional physical disk needs to be added and the system does not support hot-swapping, the system must
be turned o.
OCE/Recongure enables you to increase the total storage capacity of a virtual disk by integrating unused storage with the virtual
disk.
