Solstice Disk Suite 4.2.1 – Solaris 8

Solstice Disk Suite 4.2.1 – Solaris 8

This document details the configuration of Solstice Disk Suite 4.2.1 on a Sun V880 with Solaris 8 2/02 installed. It walks the user through a typical Disk Suite install (mirror the boot disk, stripe & mirror the file systems across the remaining disks). It also covers steps that the Disk Suite documentation leaves out (format, fmthard, and cylinder calculations). The install and configurations are accomplished via the command line and configuration files. In this example, the server only has one controller in its internal disk array. Ideally, file systems should be striped across disks and mirrored across controllers (for performance and redundancy, respectively).

Disk Suite provides the ability to grow boot disk file systems on the fly. It does not give the same flexibility for the remaining disks. They must be formatted with future file systems in mind. The file systems are static once created, as they reside on disk slices. This document divides disk space evenly between the available slices (30 GB disk = 6 X 5 GB slices). A striped file system must reside on at least 2 disks. This makes the smallest file system 10 GB. An alternative would be to purchase Veritas Volume Manager. It encapsulates entire disks, allowing for more granular management.

During the Solaris installation, ensure there is at least 15 MB on slice 7 of the boot disk. Disk Suite requires this space for the meta database.

SECTION I. INSTALL DISK SUITE

Insert the Solaris 8 Software, Disk 2 CD-ROM.

# cd /cdrom/cdrom0/Solaris_8/EA/products/DiskSuite_4.2.1/sparc/Packages

# pkgadd –d .

Respond: all, y, y, y

SECTION II. MIRROR THE BOOT DISK

COPY THE BOOT DISK’S PARTITION SIZES TO THE MIRROR

# prtvtoc -h /dev/rdsk/c1t0d0s2 > /opt/admin/docs/prtvtoc.txt (Saved the partition sizes to a file)

# fmthard -s /opt/admin/docs/prtvtoc.txt /dev/rdsk/c1t1d0s2 (formatted the spare disk with the same partition sizes as the boot disk)

fmthard: New volume table of contents now in place.

VERIFY THAT THE PARTITION TABLE WAS ACTUALLY COPIED

COMMENT: "-m 2" = 2% of the disk will be set aside for the file system configurations. The default is 10%.

The drawback to this is the superblock is different from the norm. If you need to restore, you must have

the superblock information in bold above.
