Solution  1018563.1 :   Sun StorEdge[TM] SAM-FS: Imported media has incorrect media type  


PreviouslyPublishedAs

Symptoms
When using an ACSLS library and importing media, the wrong media type is assigned.

For example, two virtual libraries are defined in the mcf file with two media types, li and lt:


# Equipment                   Eq   Eq  Family Device Additional
# Identifier                  Ord Type  Set   State  Parameters
#-----------                  --- ---- ------ ------ ----------
/etc/opt/SUNWsamfs/stkli       60   sk  stkli   on   /var/opt/SUNWsamfs/catalog/L700_li_cat
/dev/rmt/0cbn                  61   li  stkli   on
/dev/rmt/1cbn                  62   li  stkli   on
/dev/rmt/2cbn                  63   li  stkli   on
/dev/rmt/3cbn                  64   li  stkli   on
# Equipment                   Eq   Eq  Family Device Additional
# Identifier                  Ord Type  Set   State  Parameters
#-----------                  --- ---- ------ ------ ----------
/etc/opt/SUNWsamfs/stklt       70   sk  stklt   on   /var/opt/SUNWsamfs/catalog/L700_lt_cat
/dev/rmt/4cbn                  71   lt  stklt   on
/dev/rmt/5cbn                  72   lt  stklt   on
/dev/rmt/6cbn                  73   lt  stklt   on
/dev/rmt/7cbn                  74   lt  stklt   on


And within ACSLS, a scratch pool is defined with two LTO2 tapes:
2005-06-15 09:01:27              Scratch Status
Scratch Pool  Identifier  Home Location    Status     Type
7            SAM000        0, 0, 2, 1, 3  home       LTO-200G
7            SAM500        0, 0, 3, 0, 1  home       LTO-200G


The tapes are then imported using the -c and -s options:
# import -c 2 -s 7 60 (eq of li library)


However the tapes appear in the catalog as 'lt':
# Index  VSN     Barcode  Type   PTOC   ...
0      SAM000  SAM000   lt     0      ...
1      SAM500  SAM500   lt     0      ...

Resolution
The media type for imported media is inherited from the drive type. In the mcf file, the drives are defined as li, but SAM-FS assigns the media type after initialization.
Looking at the device log for drive 61, we see that the drive is initializing as a DLT7000:

2005/06/14 16:17:19*0000 Initialized. tp
2005/06/14 16:17:21*1002 Device is QUANTUM , DLT7000
2005/06/14 16:17:21*1003 Serial PXA51S0814, rev 276Aqj
2005/06/14 16:17:21*1005 Known as DLT Tape(lt)


This is more easily seen in the 'samcmd s' output which reports drives 61-64 are 'lt' and drives '71-74' are 'li'.  The complete opposite of what we have defined in the mcf file.

This is usually an indication that the wrong /dev/rmt/ entries were configured in the mcf file.  We must correct the mcf file and stk params files to correctly represent the drive type and location with the library.

Technical Instruction <Document: 1006246.1> can be used as a reference, but since we're using ACSLS and different media, it might be best to turn SAM-FS library interaction off with with 'samd stop' then run through the following:

1.  Use 'samd stop' to prevent SAM-FS from loading any tapes.
2.  Make sure all drives are empty
3.  With ACSLS, move the appropriate media into the first drive
4.  Check each /dev/rmt/# for a tape
    # mt -f /dev/rmt/0 status
    /dev/rmt/0: no tape loaded or drive offline
    # mt -f /dev/rmt/1 status
    ...
5.  Once found, note which /dev/rmt/ entry corresponds to this drive
    and dismount the media.
6.  Mount the appropriate media into the next drive.
7.  Continue with steps 4-6 until you've identified the appropriate /dev/rmt/#
    entry for each drive.
8.  Once all drives are identified, modify the mcf file and stk params file
    appropriately.
9.  Use samd config to reread the mcf file and stk params files, then verify the
    drives within 'samcmd s' are showing the appropriate media type after they
    initialize.
