Installation guide
install_type upgrade
root_device rootdisk.s0
backup_media local_filesystem /backup
layout_constraint rootdisk.s0 changeable
layout_constraint rootdisk.s7 available
The DSR upgrade fails with the following error message:
Auto-layout could not determine how to reallocate space on the file systems
with the constraints you specified. Try other constraints
Workaround: Label the rootdisk.s1 and rootdisk.s6 slices as “changeable”. If an extra disk
is available in the system, and there is sucient space on an unused slice for a backup, then
modify the <backup_media> keyword, as shown in the following example:
backup_media local_filesystem /dev/dsk/c0t1d0s7
In this example, disk c0t1d0s7 is the second disk available, and the disk has enough space for a
backup. Alternately, if there is only one rootdisk in the system, perform the backup on a remote
system. Use the following syntax:
backup_media remote_filesystem hostname:/export/backup
The DSR upgrade will succeed.
System Panic Due to lgrp_* Functions During OS
Installation (6834743)
On multi-socket Nehalem systems, where DIMMs are installed on only one CPU, the system
panics during boot with the following kernel panic error message:
Too many lgrps for platform (4)
Workaround: Disable the use of the ACPI System Resource Anity Table (SRAT) by
performing one of the following two options:
■
Boot into kmdb(1) by adding '-k' to the GRUB menu kernel line, booting, and typing the
following commands to kmdb(1):
lgrp_plat_srat_enable/W 0
:c
■
When the system is booted, set the <lgrp_srat_enable> boot property to 0 using
eeprom(1M). This setting disables the use of SRAT across reboots.
