Unknown/Raw, UPM Format | HP Surestore SAN Manager LM Software

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.
