/cx show achip
The /cx show achip command shows the SAS+SATA I/O controller (IOC)
version of the specified controller /cx.
Example:
//localhost> /c0 show achip
/c0 ACHIP Version = 3.x
/cx show allunitstatus
The /cx show allunitstatus command presents a count of total and Not
Optimal units managed by the specified controller /cx.
Example:
//localhost> /c0 show allunitstatus
/c0 Total Optimal Units = 2
/c0 Not Optimal Units = 0
/cx show autocarve
The /cx show autocarve command shows the Autocarve policy. If the policy
is on, all newly created or migrated units larger than the carvesize are
automatically carved into multiples of carvesize volumes plus one remainder
volume. You can treat each volume as an individual drive with its own file
system. The default carvesize is 2 TB. For more information see, “/cx show
memory” on page 39.
For operating systems that support units larger than 2 TB, do not 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 best to keep the policy on unless
your operating system supports disks larger than 2 TB.
When the Autocarve policy is off, all newly created units consist of one single
volume.
Example :
//localhost> /c0 show autocarve
/c0 Autocarving Policy = on
/cx show autorebuild
The /cx show autorebuild command shows the Autorebuild policy. If you
enable the policy, the firmware selects drives to use for rebuilding a degraded
unit by using the following priority order. For more information, see “/cx set
autorebuild=on|off” on page 69.
1. Smallest usable spare.
2. Smallest usable unconfigured (available) drive.
