Syntax
start secureErase (Drive [enclosureID,drawer ID,slotID] |
Drives [enclosureID1,drawerID1,slotID1 ... enclosureIDn,drawerIDn,slotIDn])
Parameters
Parameter Description
Drive or Drives
EnclosureID1,drawerID1,slotID1 ...
enclosureIDn,drawerIDn,slotIDn is for enclosures with
multiple disk drive drawers. For enclosures without disk
drive drawers, use enclosureID1,slotID1 ...
enclosureIDn,slotIDn instead Enclosure ID values are
0 to 99 .
Drawer ID values are
1
to
5
. Slot ID values are
1
to
32
.
Enclose the values in square brackets ([ ]).
Notes
Note:
The controller firmware creates a lock that restricts access to the FDE drives. FDE drives have a state
called Security Capable. When you create a security key, the state is set to Security Enabled, which
restricts access to all FDE drives that exist within the storage subsystem.
Start Performance Read Cache performance modeling
This command starts performance modeling for the Performance Read Cache. Performance modeling
monitors and measures I/O activity for a period of time and estimates performance for various
Performance Read Cache sizes. Performance is estimated using two metrics: cache hit percentage and
average response time. The performance modeling data is not available until you stop the operation
using the
stop performanceReadCache performanceModeling
command.
Syntax
start performanceReadCache [performanceReadCacheName] performanceModeling
Parameter
Parameter Description
performanceReadCache
The alphanumeric identifier (including - and _) of the
Performance Read Cache that you want to locate. Enclose
the identifier in square brackets ([ ]). If the Performance
Read Cache name contains special characters or consists
only of numbers, you also must enclose the identifier in
double quotation marks (" ") inside square brackets.
Notes
Performance modeling ends and the performance modeling data is available when one of the following
conditions occurs:
v
Run the
stop performanceReadCache performanceModeling
command.
v Retrieve the performance modeling data using IBM System Storage DS Storage Manager.
Performance modeling ends, but no data is available when one of the following conditions occurs:
