Use the VVolForSnapshot parameter to specify virtual volumes, which are usable as S-VOLs, that the SMI-S provider can use when you operate Thin Image (HTI only) from CreateElementReplica of HITACHI_ReplicationService.

All virtual volumes are specified by default.

Setting up the VVolForSnapshot parameter

Set up the parameter by using <RangeOfVVol> and <SingleVVol> with a comma (,) as a delimiter:

  • <RangeOfVVol>: Specifies a range of virtual volumes
  • <SingleVVol>: Specifies a single virtual volume

<RangeOfVVol> format

<S2HexLDKC>:<S2HexCU>:<S2HexLDEV>to<E2HexLDKC>:<E2HexCU>:<E2HexLDEV>

  • <S2HexLDKC>: LDKC number (two-digit hexadecimal) of the first virtual volume in the specified range
  • <S2HexCU>: CU number (two-digit hexadecimal) of the first virtual volume in the specified range
  • <S2HexLDEV>: LDEV number (two-digit hexadecimal) of the first virtual volume in the specified range
  • <E2HexLDKC>: LDKC number (two-digit hexadecimal) of the last virtual volume in the specified range
  • <E2HexCU>: CU number (two-digit hexadecimal) of the last virtual volume in the specified range
  • <E2HexLDEV>: LDEV number (two-digit hexadecimal) of the last virtual volume in the specified range

<SingleVVol> format

<2HexLDKC>:<2HexCU>:<2HexLDEV>

  • <2HexLDKC>: LDKC number (two-digit hexadecimal) of the single virtual volume to be specified
  • <2HexCU>: CU number (two-digit hexadecimal) of the single virtual volume to be specified
  • <2HexLDEV>: LDEV number (two-digit hexadecimal) of the single virtual volume to be specified

Example

VVolForSnapshot=00:00:00to00:00:FF,00:02:00,00:04:00to00:04:FF

In this example, a virtual volume having one of the following LDEV IDs is used as the snapshot target:

  • From 00:00:00 (LDKC=0,CU=0,LDEV=0) to 00:00:FF (LDKC=0,CU=0,LDEV=255)
  • 00:02:00 (LDKC=0,CU=2,LDEV=0)
  • From 00:04:00 (LDKC=0,CU=4,LDEV=0) to 00:04:FF (LDKC=0,CU=4,LDEV=255)
