Hi,

We are using Solaris 10; SUN cluster; Veritas Volume Manager and HDS storage with true copy (replication).

Below is the output of "vxdisk -e list":

# vxdisk -e list

DEVICE       TYPE           DISK        GROUP        STATUS               OS_NATIVE_NAME   ATTR       

:

tagmastore-usp1_242a auto:cdsdisk   lmsora-dg01a  lmsora-dg   online               c8t60060E8005654E000000654E0000242Ad0s2 tc-pvol     

tagmastore-usp1_242c auto:cdsdisk   lmsora-dg02a  lmsora-dg   online               c8t60060E8005654E000000654E0000242Cd0s2 std     <------------    

:

Query: How to change "std" to "p-vol" in the attr column?

Note: The device has already configured in pair with the secondary.

Thanks in advance.

Hi,

managed to bring the attr to "p-vol" by using the following command:

vxdisk scandisks

Thanks.

Hi,

BTW, does it matter if it is "std" while it should be "p-vol"?

'Extended attributes' are linked to ASL's that will report device attributes. 

Extract from SF 5.0 MP3 Admin Guide:

The following are the list of attributes recognized by Hitachi arrays
 
• STD This is the standard HDS device and is not involved in any special
• PVOL Shadow image primary/original device
• SVOL Shadow image secondary/clone device
• TC-PVOL Truecopy primary/original device
• TC-SVOL Truecopy secondary/clone device
• VVOL Quick shadow device
• HDP Hitachi Dynamic provisioning volume

Hi Marianne,

What is the implication if it shows std but True copy has already been configured from the storage side?

I cannot see that there will be any 'implication'. 
VxVM is simply recognizing what the ASL is reporting.

If changes have been made at array level, a quick rescan (vxdctl enable) should pick up lun attributes.
