Description
Error Message
No error code is indicated.
The 'vxdisk list' output will be similar to the following example:
# vxdisk listDEVICE TYPE DISK GROUP STATUSdisk_0 auto:sliced - - onlinedisk_1 auto:none - - online invalidemc_0_0 auto:sliced - - onlineemc0_1 auto:cdsdisk - - online thinemc0_2 auto:cdsdisk - - online thinemc0_3 auto:cdsdisk - - online thin
The expected output would be similar to:
# vxdisk listDEVICE TYPE DISK GROUP STATUSdisk_0 auto:sliced - - onlinedisk_1 auto:none - - online invalidemc_0_0 auto:sliced - - onlineemc0_1 auto:cdsdisk - - online thinrclmemc0_2 auto:cdsdisk - - online thinrclmemc0_3 auto:cdsdisk - - online thinrclm
Cause
There is a known incident (2147922) for the Array Support Library used with EMC VMax where LUNs are not indicated as 'thinrclm'. This is fixed in Storage Foundation 5.1SP1 and later.
The VMax storage array code may not be at the required level to display "thinrclm" LUNs.
Resolution
To correctly see LUNs as "thinrclm", and not as "thin" the following conditions must be met:
1) Storage Foundation / Volume Manager 5.1 SP1 must be installed.
2) The VMax storage array code must be at code level 5875 or later to properly indicate "thinrclm" LUNs.
Resolve the issue by meeting the above requirements.
Applies To
Linux RHEL5
Storage Foundation 5.1
Volume Manager 5.1
