If MB or GB is used, then it should not be more than available size of Drive Group.
e.g. if available size of Drive Group(DRIVEGRPNAME) is 2346MB it should be less than
or equal to ’2346MB’ or ’2GB’. The SIZE specified should be whole numbers
i.e. 236.54MB is not a valid number.
UNIT : Unit of the size can be GB or MB or %
READCMDSIZE : Sequential Post Read Command Size is the maximum sector count of a single
predictive read ahead. A value of 0 disables predictive read for this volume.
A value of 1-128 will override the previous setting and represents a command
transfer size that is a multiple of 16Kbytes. A value of (0xFFFF) will cause
the default value to be used.
MARGIN : Read Ahead Margin is the number of sectors in the read ahead buffer. This parameter
is ignored if the Sequential Post Read Command Size is zero. The valid range is 1
to 0x7FFF. A value of (0xFFFF) results in the default value being used.
In other words, specify size in MB, GB or percentage of the total pool capacity.
Specify the name as
poolname:volumename
. The volume name can be a maximum of
12 characters long and can contain alphanumeric and underscores. Make the
volume name unique across the pool on which it is being created. The maximum
sector count of a single predictive read ahead is
seqpostreadcmdsize
. A value of 0
disables predictive read for this volume. A value of 1-128 overrides the previous
setting and represents a command transfer size that is a multiple of 16Kb. A value
of (0xFFFF) causes the default value to be used. The number of sectors in the read
ahead buffer is
seqreadaheadmargin . This parameter is ignored if the
seqpostreadcmdsize is zero. The valid range is 1 to 0x7FFF. A value of (0xFFFF)
results in the default value.
Example:
<CLI> create volume –name Grp1:volume1 –size 10 %
Volume 'volume1' created on pool 'Grp1' with capacity 15 GB.
delete pool
This command deletes a drive pool.
Command arguments:
<CLI> delete pool –name poolName
Where:
v poolName
- Specifies name of pool to be deleted.
When you issue this command, the following warning is appears:
Example:
<CLI> delete pool –name Group0
All volumes in this Pool and hostluns mapped to them will be
unavailable (deleted). The data for these volumes will be deleted.
Do you want to continue? Type L to delete or any other key to cancel.
L
Pool Group0 has been deleted.
An error message is displayed if the target pool is not found.
Example:
<CLI> delete pool –name Group0
No such drive pool
Please re-execute the command with valid pool name available
