Hitachi TrueCopy paircreate EX_CMDRJE

dr_gsb — Mon, 01 Nov 2010 05:34:24 GMT

Hi all,
I am trying to establish replication of Hitachi luns using TrueCopy. I have masked only the Command Device to the management server. The production hosts are seeing the data luns. I changed the "Raid Manager protect" flag to "Disabled" for this.
I am able to see the status of the luns using pairdisplay:
C:\HORCM\etc>pairdisplay -g htc1
Group PairVol(L/R) (Port#,TID, LU),Seq#,LDEV#.P/S,Status,Fence,Seq#,P-LDEV# M
htc1 htc1_000(L) (CL2-B , 1, 327) 5214 327.SMPL ---- ------,----- ----- -
htc1 htc1_000(R) (CL2-B , 1, 232) 8147 232.SMPL ---- ------,----- ----- -
htc1 htc1_001(L) (CL2-B , 1, 328) 5214 328.SMPL ---- ------,----- ----- -
htc1 htc1_001(R) (CL2-B , 1, 233) 8147 233.SMPL ---- ------,----- ----- -
htc1 htc1_002(L) (CL2-B , 1, 329) 5214 329.SMPL ---- ------,----- ----- -
htc1 htc1_002(R) (CL2-B , 1, 234) 8147 234.SMPL ---- ------,----- ----- -

But when I issue paircreate, it fails with an error:
C:\HORCM\etc>paircreate -g htc1 -vl -f data
paircreate: [EX_CMDRJE] An order to the control/command device was rejected
Refer to the command log(C:\HORCM\log2\horcc_vcslx087vm1_log.txt) for details.
It was rejected due to SKEY=0x05, ASC=0x95, SSB=0x8400,0x0032 on Serial#(5214)

The log doesn't contain much info:
CMDLINE : paircreate -g htc1 -vl -f data
11:43:47-dac00-02920- ERROR:cm_sndrcv[rc < 0 from HORCM]
11:43:47-dac00-02920- [paircreate] L_CMD(CREATEPAIR) ERROR :rc = -35
11:43:47-dac00-02920- [paircreate][exit(221)]
[EX_CMDRJE] An order to the control/command device was rejected
[Cause ]: An order to the command(control) device failed,or was rejected.
[Action]:Please confirm the following items.If this trouble doesn't resolve,then collect HORCM error logs(HORCM_LOG=C:\HORCM\log2\curlog) and Remote HORCM logs,and send them to service personnel.
(1) Check if the 'HORC or HOMRCF function' is installed in the RAID.
(2) Check if the RCP and LCP are installed in the RAID.
(3) Check if the path between the RAID CUs is established by using the SVP.
(4) Check if the pair target volume is an appropriate status.

I've checked that the 4 items listed above are satisfied.

Can someone help me here?

Thanks in adv

I have hand edited the conf file since the mgmt server doesn't see other data luns.

I now even masked the data luns to the mgmt server. But paircreate returns the same error.

Btw, both the hosts involved (mgmt servers) are Virtual Machines on Vmware ESX 4.0.
The Command devices and the data luns are shown as Raw Device Mappings to the VMs.

Are the Remote devices presented to a host group? They need to be iirc. I have a dummy group we use for some of this stuff, with no wwn's assigned to it.

I used a different (old) lun in the horcm conf file and it worked!
It still doesn't work with the new luns that I had just created and added in the conf file.

All the luns are already part of some host port group. I didn't understand what you meant by 'iirc'?
