Array Firmware

• HIT/Linux requires PS Series array firmware version 9.0 or later.

• The capability to import EqualLogic storage to PowerStore requires PS Series array firmware version 10.0.3.

Supported File Systems

ASM/LE supports the following Linux file system types: ext3, ext4, xfs, and gfs2.

The following table describes file system restrictions when using ASM/LE.

File System

Restriction

ext2, btrfs

Not supported by ASM/LE; displays an error message when you attempt to create a Smart Copy.

ext3, ext4, xfs

Read-write on SLES 12 and later.

NOTE: Select ext4 or xfs when installing SLES 12. The default file system installed during

SLES 12 installation is btrfs, which is not supported by ASM/LE.

ocfs2

ASM/LE does not support the cluster file system ocfs2.

gfs2

Supported on SLES 12 and later.

NOTE: Unsupported file systems might not allow file-system freeze and thaw operations. Without the ability to freeze

all of the data at once, ASM/LE cannot create consistent Smart Copies.

Use of the multipathd Daemon

The multipathd daemon is not required for EqualLogic devices. Blacklist Dell EqualLogic devices so multipathd does not attempt to

manage them. For more information, see Migrating to HIT/Linux Multipath I/O. However, the multipathd daemon is required to

manage PowerStore devices. Therefore, to import EqualLogic storage to PowerStore, make sure that the multipathd service is

running. For more information see Importing External Storage to PowerStore Guide.
