6. Create the storage units that will be used for the Tru64 UNIX and
TruCluster Server filesystems. Example 4-10 uses the information from
Table 4-2 and four 9.2-GB disks to provide RAID0+1. If you select
RAID1 (mirroring) and have more than one mirrored pair (4, 6, 8, and
so forth disks) data is automatically striped to provide RAID0+1.
Example 4-10: Creating the Storage Units (LUNs)
MSA1000-1> ADD UNIT 1 RAID_LEVEL=1 DATA="DISK101 DISK102 DISK108 DISK109" SIZE=2GB 1
First volume to be configured on these drives.
The logical unit size has been adjusted by 1MB for optimal performance.
Logical Unit size = 2047 MB
RAID overhead = 2047 MB
Total space occupied by new unit = 4094 MB
Free space left on this volume: = 134827 MB
2
Unit 1 is created successfully.
MSA1000-1> ADD UNIT 2 RAID_LEVEL=1 DATA="DISK101 DISK102 DISK108 DISK109" SIZE=2GB
3
The logical unit size has been adjusted by 1MB for optimal performance.
Logical Unit size = 2047 MB
RAID overhead = 2047 MB
Total space occupied by new unit = 4094 MB
Free space left on this volume: = 130732 MB
Unit 2 is created successfully.
MSA1000-1> ADD UNIT 3 RAID_LEVEL=1 DATA="DISK101 DISK102 DISK108 DISK109" SIZE=8GB
4
The logical unit size has been adjusted by 3MB for optimal performance.
Logical Unit size = 8189 MB
RAID overhead = 8189 MB
Total space occupied by new unit = 16378 MB
Free space left on this volume: = 114354 MB
Unit 3 is created successfully.
MSA1000-1> ADD UNIT 4 RAID_LEVEL=1 DATA="DISK101 DISK102 DISK108 DISK109" SIZE=6GB
5
The logical unit size has been adjusted by 2MB for optimal performance.
Logical Unit size = 6142 MB
RAID overhead = 6142 MB
Total space occupied by new unit = 12284 MB
Free space left on this volume: = 102068 MB
Unit 4 is created successfully.
