Importing Disk Sets

importing a disk set

The metaimport command allows you to import disk sets from one system to another.

How to Print a Report on Disk Sets Available for Import

  1. Become superuser.
  2. Obtain a report on disk sets available for import.
    # metaimport -r -v
    -r

    Provides a report of the unconfigured disk sets available for import on the system.

    -v

    Provides detailed information about the state database (metadb) replica location and status on the disks of unconfigured disk sets available for import on the system.

Example 19-13 Reporting on Disk Sets Available for Import

The following examples show how to print a report on disk sets available for import. The output from the metaimport command distinguishes between regular disk sets and replicated disk sets.

# metaimport -r
Disksets eligible for import:

1)  Found replicated diskset containing disks :
  c1t2d0
  c1t3d0
    Creation time:      Tue May 3 14:27:29 2006
For more information about this set:
  metaimport -r -v c1t2d0
To import this set:
  metaimport -s <newsetname> c1t2d0


2)  Found replicated diskset containing disks :
  c1t12d0
  c1t9d0
    Creation time:      Tue May 3 14:30:00 2006
For more information about this set:
  metaimport -r -v c1t12d0
To import this set:
  metaimport -s <newsetname> c1t12d0

Number of disksets eligible for import: 2

# metaimport -r -v c1t2d0
Disksets eligible for import:

1)  Found regular diskset containing disks:
  c1t2d0
  c1t3d0
    Metadatabase information:
        flags           first blk       block count
         a        u     16              8192            /dev/dsk/c1t2d0s7
         a        u     16              8192            /dev/dsk/c1t3d0s7

    Metadevice information:

    Creation time:      Tue May 23 13:05:39 2006
    Last modified time: Tue May 23 13:05:39 2006
    To import this diskset:
      metaimport -s <newsetname> c1t2d0

The following output of metaimport -r reports the following conditions in the system's disk set configuration.

  • A partial disk set in which one or more disks are unavailable

  • Disk conflicts where the disk is detected in more than one disk set

  • A replicated disk set

  • The recommended disk set to import


    Note - A disk can also be reported as unavailable and in conflict at the same time.


# metaimport -r

Disksets eligible for import:

1)  Found partial regular diskset containing disks:
  c1t2d0 (CONFLICT)
  c3t50020F230000FA57d0 (UNAVAIL)
  c3t50020F230000FA57d1 (UNAVAIL)
    (UNAVAIL) WARNING: This disk is unavailable on this system.
    Import may corrupt data in the diskset.

    (CONFLICT) WARNING: This disk has been reused 
in another diskset or system c onfiguration.
    Import may corrupt data in the diskset.

    Creation time:      Tue May 23 13:05:39 2006
    For more information about this diskset:
      metaimport -r -v c1t2d0
    To import this diskset:
      metaimport -f -s <newsetname>  c1t2d0


2)  Found regular diskset containing disks:
  c1t2d0 (CONFLICT)
  c1t3d0
  c1t4d0
    (CONFLICT) WARNING: This disk has been reused 
in another diskset or system c onfiguration.
    Import may corrupt data in the diskset.


    Creation time:      Tue May 23 13:04:57 2006
    For more information about this diskset:
      metaimport -r -v c1t3d0
    To import this diskset:
      metaimport -f -s <newsetname> c1t3d0


3)  Found replicated diskset containing disks:

    Creation time:      Thu May 25 14:56:13 2006
    For more information about this diskset:
      metaimport -r -v c3t50020F23000100F7d13
    To import this diskset:
      metaimport -s <newsetname> c3t50020F23000100F7d13


Number of disksets eligible for import: 3

Warning:  The following disks have been detected in more than one set.
Import recommendation based upon set creation time.
Proceed with the import with caution.
  c1t2d0  - must import with set created at : Tue May 23 13:05:39 2006
#

Importing a disk set is blocked if the disk set has disk conflicts. The preceding example recommends that c1t2d0 be imported with the set created at 13:05:39 on Tuesday, May 23. If you import a different disk set instead, the following message is displayed:

# metaimport -f -s <setname> c1t3d0

  Importing regular diskset containing disks:
   c1t2d0 (CONFLICT)
   c1t3d0
   c1t4d0

     (CONFLICT) WARNING: This disk has been reused in another diskset 
or system configuration.
     Import may corrupt data in the diskset.

      Creation time:      Tue May 23 13:04:57 2006

   Warning:  The following disks have been detected in more than one set. 
Import recommendation based upon set creation time. 
Proceed with the import with caution.
   c1t2d0  - must import with set created at : Tue May 23 13:05:39 2006 
To import this set, c1t2d0 must be removed from the system

How to Import a Disk Set From One System to Another System

  1. Become superuser.
  2. Verify that a disk set is available for import.
    # metaimport -r -v
  3. Import an available disk set.
    # metaimport -s diskset-name disk-name
    - s diskset-name

    Specifies the name of the disk set being created.

    disk-name

    Identifies a disk (c#t#d#) containing a state database replica from the disk set being imported.

  4. Verify that the disk set has been imported.
    # metaset -s diskset-name
Example 19-14 Importing a Disk Set

The following example shows how to import a disk set.

# metaimport -s red c1t2d0
Drives in diskset including disk c1t2d0:
  c1t2d0
  c1t3d0
  c1t8d0
# metaset -s red


Set name = red, Set number = 1

Host                Owner
  host1            Yes

Drive    Dbase

c1t2d0   Yes  

c1t3d0   Yes  

c1t8d0   Yes
