HP SureStore E SAN Manager LUN Management Solaris Installation Guide

20 Supported Partition Map Formats
Supported Partition Map Formats
Using the SAN Manager LM application on a Windows NT node, you can assign the
following types of LUNs (devices) to Solaris nodes: Unknown/Raw, NTFS/FAT, and UPM
format. If you intend to use these types of LUNs in a Solaris environment, the necessary
Solaris file systems (UFS or VxFS) must be created.
Unknown/Raw
Unknown/raw disks are displayed with device names in /dev/rdsk and /dev/dsk on Solaris
nodes. These device names are used to build UFS or VxFS (Veritas) file systems using the
Solaris Format utility.
NTFS/FAT
NTFS/FAT disks are displayed as usable devices on Solaris nodes.
Caution To use an NTFS/FAT device on a Solaris node, you must format it with a UFS
or VxFS file system, which will erase Microsoft s FAT/NTFS file system and all
data on the disk prior to Solaris formatting.
UPM Format
There are three types of UPM partitions that exhibit the following behavior when UPM
devices are assigned to Solaris nodes:
• Database: Used in the SAN Manager LM database mirror set. Database partitions are not
accessible to Solaris nodes.
• Free space: Unused space on a UPM disk is called free space. Free space partitions are
not accessible to Solaris nodes.
• File system: This UPM partition is designated for use as a file system partition. UPM file
system partitions are displayed as Virtual LUNs on Solaris nodes. A Virtual LUN is really
a single UPM partition on a disk, but Solaris views it as a usable device that can be
partitioned and used for up to seven UFS file systems.
