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:
- 2 Solaris nodes in a 6.0 SFCFS cluster - sol25 and sol26
- Took down 1 of the solaris nodes - sol26
- Left DG imported on remaining solars node sol25
- Reinstalled rhel26 as RHEL 6 - Didn't check DG status on sol25
- 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.
- 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 errorThe steps to resovle the issue:
- format -> select the disk -> fdisk
- check disks status - online
- /etc/vx/cbr - vxconfigrestore DG
