/cx show achip
For 9750 and 9690-SA controllers, this command displays the SAS+SATA
IOC (i/o controller) version of the specified controller /cx. For older
controllers, this command reports the ACHIP (ATA Interface Chip) version of
the specified controller /cx.
Example:
//localhost> /c0 show achip
/c0 ACHIP Version = 3.x
/cx show allunitstatus
This command presents a count of total and Not Optimal units managed by
the specified controller /cx. For more about the meaning of Not Optimal, see
“Shell Object Commands” on page 24.
Example:
//localhost> /c0 show allunitstatus
/c0 Total Optimal Units = 2
/c0 Not Optimal Units = 0
/cx show autocarve
This feature only applies to 9750 controllers and 9000 series SX/SE/SA
controllers.
This command reports the Auto-Carve policy. If the policy is on, all newly
created or migrated units larger than the carvesize will be automatically
carved into multiples of carvesize volumes plus one remainder volume. Each
volume can be treated as an individual drive with its own file system. The
default carvesize is 2TB. For more information see, “/cx show memory”,
below.
For operating systems that support units larger than 2TB, there is no need to
set the policy to on unless you want the operating system to have multiple
smaller volumes.
If you use a 32-bit operating system, it is recommended that you keep the
policy on unless you know that your operating system supports disks that are
larger than 2 TB.
When the autocarve policy is off, all newly created units will consist of one
single volume.
Example :
//localhost> /c0 show autocarve
/c0 Auto-Carving Policy = on
