Parameters

Options

Keyword identifying one or more of the following options:

  • NAME—alias for a virtual pool or virtual volume. Maximum length is 31 characters. Default is pool# or volume#.
  • DESCRIPTION—device description for a virtual pool or virtual volume. Maximum length is 31 characters.
  • CHUNK (virtual pool only)—chunk size, in kilobytes, for the virtual pool. Valid values are:
    • 64, 256, 1024, 4096
    • Default chunk size is 256KB
  • FFMODE (virtual volume only)—fetch and flush rate for the virtual volume. Valid values are:
    • 1-Aggressive
    • 2-Normal (default)
    • 3-Passive
LEVEL <level>
Indicates the tier level of a virtual pool. Valid values are:
  • 0-Upper tier (fastest media)
  • 1-Lower tier (slower media)
LD#
Logical drive number(s) for a virtual pool or cached logical drive. Virtual pools support a maximum of eight logical drives. Cached logical drives support exactly one logical drive.
Cache Mode
Indicates the cache mode for a cached virtual volume. Valid values are:
  • WTCACHE — Enables write through cache. Uses the cache for fast retrieval and updates primary storage at the same time.
  • WBCACHE — Enables write back cache. Uses cache for the "freshest" data and updates primary storage at a later time.
Note: For a cached LD volume, the cache mode defaults to Write-Through.
Cache Size
In a cached logical drive, indicates the size of the cache, in gigabytes, in the Tier 0 virtual pool.
<Tier0 Pool#> <Size from Tier0 Pool>
Tier 0 virtual pool number and pool size, in gigabytes. Use MAX to use all available pool space.
<Tier1 Pool#> <Size from Tier1 Pool>
Tier 1 virtual pool number and pool size, in gigabytes. Use MAX to use all available pool space.
noprompt
Suppresses the confirmation prompt.
