Solution 1527222.1 : ACSLS - L700 not fully communicating with ACSLS after MPC and MPU2 cards replaced

Applies to:

Sun StorageTek L700 Tape Library - Version Not Applicable to Not Applicable [Release N/A]
Sun StorageTek Auto Cartridge Sys Lib SW (ACSLS) - Version 7.1 to 8.2 [Release 7.0 to 8.0]
Information in this document applies to any platform.

Symptoms

1. The ACSLS testports utility returns "LSM becoming ready" message with error 62800.

    $ testports
     acs 0 | port 0 | /dev/mchanger0 | offline | LSM error 62800: \c LSM becoming ready

    $ smc_test /dev/mchanger0:
    ..
    Command: n
    Peripheral Type = 8
    Vendor ID = “STK”
    Product ID = “L700”
    Revision Level = “0317”
    PTP Serial Number = “MPC74001967”
    Vendor Specific ID = 005da630
    Vendor Specific ID Extn = 113085014f0

Command: s 29
Command error = 62800

    Command: t
    Command error = 62800

    Command: i
    Command error = 62800

    NOTE: Error 62800 refers to:
    SK/ASC/ASCQ 6/28/00 = 28/00 DTLPWROMAEBKVF NOT READY TO READY CHANGE, MEDIUM MAY HAVE CHANGED
    i.e., the LSM is not getting to a ready state

2. acsss_config may also show the 62800 error:

$ acsss_config

8. Define or Change Library Configuration

Menu choice: 8

    Verifying database environment…
    Configure library communications? (y or n): y
    Library server data base exists and will be overwritten, continue (y or n)? y
    Number of connections to ACS #0: 1

Device or host – ACS #0, connection #0: /dev/mchanger0

Checking defined ports…

acs 0 | port 0 | /dev/mchanger0 | offline | LSM error 62800: \c
LSM becoming ready

Each port must be attached and communicating to a functional
Library before the library can be configured. Exiting.

    Cannot execute program ‘$ACS_HOME/config/lib_config.sh’
    Acsss_config 1595: Error: Problems occurred running the configuration menu.
    Exiting

Changes

After a power outage the SL700 had hardware problems and both the MPC (communication controller board) and MPU2 ( FC board ) cards were replaced.

Cause

There is a problem with the L700 MPC board. If the OS is not able to see the L700, there may also be a problem with the MPU2 board.

Solution

1. To verify FC connectivity to the L700, refer to <Document 1020528.1> ACSLS - Troubleshooting 'mchanger' Installation Problems

2. If the the FC HBA on the ACSLS server is correctly configured, 'cfgadm -al' command should show something like this output for the HBA:

C3::500104f0005da631 med-changer connected configured unkown

3. Run the ACSLS testports utility. If testports is successful, the output will look like this:
     $ testports
        ACS0:
        /dev/mchanger0 is communicating to an LSM: STK L700 level 0317

     Otherwise, testports will return an error.

4. If testports return a 62800 error, verify if the same error is returned by the smc_test utility.
     Refer to <Document 1014616.1> ACSLS - How to run smc_test.

5. If the ACSLS utilities return the same 62800 error consistently, open a HW service request to have a field engineer
     check the library MPC and/or MPU2 cards.

6. If another type of error is being returned by the ACSLS utilities, search the Knowledge base for known solutions or
     open a service request in My Oracle Support.
