If the configuration item _hp_root_grp_striped is set to "YES" then you set up striping. The "stripes = *" set the number of stripes equal to the number of disks in the volume group. The stripe size _hp_FS_stripe_size was set up earlier as 64KB.

hp_root_grp_striped == "YES" { stripes = *

stripe_size = _hp_FS_stripe_size

}

}

The definition of /opt is very similar to the definition of /usr. For this volume and the others defined by setting "Create separate volumes (/usr, /var, ...)" to true, you only look at the differences rather than the similarities.

The only difference between /usr and /opt is the size definition: rather than giving a percentage free, there is a specific size requirement for free space. For example, in the first size definition, when the size of the root disk is <1800MB, /opt is a minimum of 100MB. After all space has been allocated, you take from the remaining up to an extra 100MB and place it into /opt38.

logical_volume { mount_point = "/opt" largefiles = true

_hp_disk_layout == "Logical Volume Manager (LVM) with HFS" { usage = HFS

blksize = _hp_HFS_blksize fragsize = _hp_HFS_fragsize

} else {

usage = VxFS

blksize = _hp_VxFS_blksize

}

disk[_hp_root_disk].size < 1800Mb { size = 100Mb remaining 100Mb free

} else {

disk[_hp_root_disk].size > 3072MB { size = 100Mb remaining 252Mb free

} else {

size = 100Mb remaining 152Mb free

}

}

_hp_root_grp_striped == "YES" { stripes = *

stripe_size = _hp_FS_stripe_size

}

}

If the size of the root disk is greater than or equal to 8192MB, the final size can be 500MB plus the size of _hp_pri_swap. The value is based on primary swap being dump and some space is required in /var/adm/crash to save crash dumps. This assumption is invalid if you define a separate volume for /var/adm/crash using the Ignite-UX GUI.39

38Again, the impact of software being installed can increase the size of this volume, and the _hp_addnl_fs_free_pct configuration item can increase the final size of the volume (if free space is still left unallocated).

39The size requirement is up to 500MB + _hp_pri_swap. Depending on free disk space, there may not be enough to increase the size of a file system this large. During an interactive installation, the size of /var can be manually tuned down to a more appropriate value.
