Problem setting up Netbackup SSO (Shared Storage Options)

Hi All,

 Our Netbackup system is version 7.5.0.4. We have 2 tape library (HP ESL322e) connect using SAN. We already had up running drives running as SSO (setup by our System Integrator). Two of  drives on the TL being shared between 2 server , one running Solaris 10 the other one AIX 6.1. in site A. There is another pair with the similar configuration on site B.

One day our HP did firmware upgrade to TL on site A. The upgrade was not smooth, I had to reconfigure again the connection on Solaris 10 (but the AIX was fine).

The problem if I setup individual tape drive to the Solaris  or AIX, the backup could run fine. Then I did the SSO with configuration like 1 only for solaris, another 1 only for AIX, but 2 other dirves I config as SSO. Then I test the backup on Solaris , it supposed can see 2 drives (1 single, 1SSO). I fired first backup it run on the Solaris, but when I run the second drive, it won' go that SSO drive, it keep on waiting for resources.

 

10/23/2013 16:17:16 - awaiting resource ESL025_EBS6_MPX. Waiting for resources.
          Reason: Drives are in use, Media server: ebs6-bck,
          Robot Type(Number): TLD(1), Media ID: N/A, Drive Name: N/A,
          Volume Pool: test1, Storage Unit: ESL025_EBS6_MPX, Drive Scan Host: N/A,
          Disk Pool: N/A, Disk Volume: N/A

notes: ebs6 is the Solaris media server.

 

What i did wrong? Why it cannot use that SSO drive?

 

Thank you and regards,

 

Iwan

  • Thanks for the output.

    Firstly, we see that stu ESL025_EBS6_MPX  is configured for 4 drives:

    Label:                ESL025_EBS6_MPX
    Storage Unit Type:    Media Manager
    Host Connection:      ebs6-bck
    Number of Drives:     4
    On Demand Only:       no
    Max MPX/drive:        12
    Density:              hcart2 - 1/2 Inch Cartridge 2
    Robot Type/Number:    TLD / 1
    Max Fragment Size:    1048575 MB

    Why is that when only 2 drives are assigned to this media server on this host?

    As I have said before, this will result in over-allocation of jobs for this STU.

    Can you confirm that SSO license key was added to both of these media servers? (Check output of get_license_key on both media servers).

    vmoprcmd tells us that NBU was probably not restarted on media server ebs7 after drives were configured as SSO?

    ESL025_Drive12           No      No                     No        hcart2
        ebs6-bck                   /dev/rmt/1cbn                        SCAN-TLD
        ebs7-bck                   /dev/rmt1.1                          RESTART

     

    NBU needs to be restarted on both media servers.

    Please correct the STU config on the master server and run 'bprdreq -rereadconfig'.

    If above steps were taken and drive 12 is still not used, try to down drive 11 on ebs6 and see if drive 12 gets used.

     

    Let us know the result.
