All disks became error


Hi,

Here's the situation:
Two nodes share the same luns, one system is Sol 10 with SFCFSHA 6.0.
Some dg/vol created and configured to 6.0 cluster.
Install another node to RHEL 6 with SFHA 6.2, after then, all the disks became error in Sol 10 node.

Sol 10 + SFCFSHA 6.0 :
[root@sol25 /]#vxdisk -oalldgs list
DEVICE       TYPE            DISK         GROUP        STATUS
disk_0       auto:none       -            -            online invalid
emc_clariion0_1 auto            -            -            error
emc_clariion0_2 auto            -            -            error
emc_clariion0_3 auto            -            -            error
emc_clariion0_4 auto            -            -            error
emc_clariion0_5 auto            -            -            error
emc_clariion0_6 auto            -            -            error

 

RHEL 6 + SFHA 6.2 :
[root@rhel26 ~]# vxdisk -oalldgs list
DEVICE       TYPE            DISK         GROUP        STATUS
emc_clariion0_1 auto:none       -            -            online invalid
emc_clariion0_2 auto:none       -            -            online invalid
emc_clariion0_3 auto:none       -            -            online invalid
emc_clariion0_4 auto:none       -            -            online invalid
emc_clariion0_5 auto:none       -            -            online invalid
emc_clariion0_6 auto:none       -            -            online invalid

How can I get the DGs back on Sol system ? Thanks in advance !

  • Thanks all !!

    The issue is resovled.

    The steps I met the issue:

    1. 2 Solaris nodes in a 6.0 SFCFS cluster - sol25 and sol26
    2. Took down 1 of the solaris nodes - sol26
    3. Left DG imported on remaining solars node sol25 
    4. Reinstalled rhel26 as RHEL 6 - Didn't check DG status on sol25
    5. Installed SFHA 6.2, NON CFS - Checked vxdisk -oalldgs list, all disks were online, but not seen deported DG on shared disk. No other operations.
    6. Ran vxdisk -oalldgs list on sol25 - all disks were error

    On sol25:

     

    # dd if=/dev/rdsk/c1t5d0s2 of=/c1t5d0s2.ddoutput bs=512 count=100000
    dd: /dev/rdsk/c1t5d0s2: open: I/O error

     

     

    The steps to resovle the issue:

    1. format -> select the disk -> fdisk
    2. check disks status - online
    3. /etc/vx/cbr - vxconfigrestore DG
