Release Notes
AA–RFBPE–TE 387372-005 Page 11
If any storageset within your configuration was previously initialized with the
INITIALIZE container-name SAVE_CONFIGURATION command to save your
configuration to disk, it will not be necessary to reconfigure your devices with a
new controller. SAVE_CONFIGURATION also retains code patch information
to the software. This option is supported on single controller configurations only.
ACS Software Version 8.5 saves any installed software patches on disks
initialized with the SAVE_CONFIGURATION option. Should you need to
replace a controller and restore the configuration from a disk, you will not have
to reinstall any software patches.
NOTE
You must use the same software version
when replacing the controller. You can also
hold in port button 6 on the operator control
panel, and press the reset button to restore
the configuration.
Configuration information cannot be retrieved from storagesets created on other
HSx controllers (for example, HSD, HSJ, or HSZ controllers). You can only
restore a configuration from a configuration saved on this or another HSG80
array controller.
7.0 HOST OPERATING SYSTEM NOTES
7.1 Maximum Supported Storageset Size
With this release, Solaris can support storagesets up to 512 GB with the
following limitations:
• You cannot enter the LUN logical geometry manually, it must be sensed by
format automatically. LUNs configured manually are still limited to 256 GB.
• You must limit the number of sectors/track to 255 and the number of heads
to 128 when the LUN is initialized. This means that you will have to use the
CLI to create and initialize LUNS to ensure that these limits are observed.
Use the command:
initialize <container> heads = 128
sectors_per_track = 255
