Post subject: | Cannot remove or create virtual volumes [SOLVED] |
Hello all, In August 2013 we have bought a 3par 7200 with SSD(8x100GB), SAS(24x600GB) and NLSAS(12x2TB) tiers. Everything runs fine and can be managed quite well. Release version 3.1.2 (MU2). Last week I've been organizing our virtual volumes a bit. Moved some VM's to other volumes. Removed some empty virtual volumes and it's vluns. Also removed some unused CPGs. All went well except for one Virtual Volume. I cannot remove 'VMFS06Volume'. It can be listed by 'showvv' and can be selected in several GUI tasks, but when trying to perform the task it says: VV VMFS06Volume not found. See the commands I used: Code: AX3PAR01 cli% showvv -d Id Name Rd Mstr Prnt Roch Rwch PPrnt PBlkRemain -------------VV_WWN------------- ------CreationTime------ 1 .srdata RW 0/1/- --- --- --- --- -- 60002AC0000000000000000100002A42 2013-09-11 19:24:18 CEST 0 admin RW 1/0/- --- --- --- --- -- 60002AC0000000000000000000002A42 2013-09-11 19:16:52 CEST 7 VMFS01volume RW 0/1/- --- --- --- --- -- 60002AC0000000000000000700002A42 2013-09-24 14:46:08 CEST 6 VMFS02volume RW 1/0/- --- --- --- --- -- 60002AC0000000000000000600002A42 2013-09-24 13:46:35 CEST 8 VMFS03volume RW 1/0/- --- --- --- --- -- 60002AC0000000000000000800002A42 2013-10-02 15:18:48 CEST 9 VMFS04volume RW 0/1/- --- --- --- --- -- 60002AC0000000000000000900002A42 2013-10-02 15:34:27 CEST 12 VMFS06Volume RW 0/1/- --- --- --- --- -- 60002AC0000000000000000C00002A42 2013-10-23 12:25:18 CEST 20 VMFS08volume RW 0/1/- --- --- --- --- -- 60002AC0000000000000001400002A42 2013-11-29 13:21:11 CET 25 VMFS09Volume RW 0/1/- --- --- --- --- -- 60002AC0000000000000001900002A42 2013-12-18 12:25:39 CET 26 VMFS10Volume RW 1/0/- --- --- --- --- -- 60002AC0000000000000001A00002A42 2014-01-07 09:54:31 CET ------------------------------------------------------------------------------------------------------------------ 10 total 0 AX3PAR01 cli% checkvv VMFS06Volume VV VMFS06Volume not found AX3PAR01 cli% removevv VMFS06Volume Removing vv VMFS06Volume select q=quit y=yes n=no: y VV VMFS06Volume not found AX3PAR01 cli% Further troubleshooting shows: - that I also cannot even create virtual volumes anymore. I create a volume at the CLI, but when I showvv. No volume has been created. - that in the GUI at Storage Systems->AX3PAR01->Virtual Volumes in the CPG Space tab, I cannot see the spreading over the tiers (I used AO until now) What can I do to fix this? Are there any services that I can restart? Any help would be very much appreciated. Thanks. |

Hereby a screenshot which shows 0GiB User Space. I used to get an overview with every volume displaying the amount of data on which tier (SSD/SAS/NLSAS).

you have an exclamation mark against your CPG's. Click into there and see what that is all about? |

That's the warning saying I have too little space left on my SSD tier. That was why I was cleaning things up and set up some new volumes in other CPGs. Growth warning at 250 GiB. Message/alert also being showed at the bottom, see screenshot.

I've never received a degraded message on a low space condition. I run my SSD at 100% all day everyday on a T400, granted only at 3.1.1MU3. I get alert messages, but never a degraded message. If you are sure, then fair enough. I've just never seen it and would investigate further. |

Ok. At first I didn't either, but when I saw AO was filling the CPG's to 100% I set the Growth Warning of SSD_r1 to 250GiB. When I remove the warning threshold, the exclamation mark dissappears. Thanks for your effort to help me though!

back to your original issue, are you using the default admin account 3paradm or another account with correct permissions? I assume so, else you would get a different error, but can't hurt to ask. Have you tried removing that volume with a pattern switch - such as: `removevv -pat VMFS06*` Else, I would be logging a support call to HP, because there isn't much else I can think of and the error messages you are getting don't really point to anything useful. |

A support call has been logged at HP. Keep you informed. |

HP Support was able to solve the problem. Executing the following command in the cli did the trick: setsysmgr clear_cache All volumes are shown correctly now via e.g. ‘showvv’, Code: AX3PAR01 cli% showvv ----Rsvd(MB)----- --(MB)-- Id Name Prov Type CopyOf BsId Rd -Detailed_State- Adm Snp Usr VSize 1 .srdata full base --- 1 RW normal 0 0 61440 61440 0 admin full base --- 0 RW normal 0 0 10240 10240 7 VMFS01volume tpvv base --- 7 RW normal 896 0 993152 2097152 6 VMFS02volume tpvv base --- 6 RW normal 1152 0 1100544 2097152 8 VMFS03volume tpvv base --- 8 RW normal 1152 0 1478784 2097152 9 VMFS04volume tpvv base --- 9 RW normal 640 0 798208 2097152 20 VMFS08volume tpvv base --- 20 RW normal 1536 0 2079360 3145728 25 VMFS09Volume tpvv base --- 25 RW normal 1408 0 1730560 4194560 26 VMFS10Volume tpvv base --- 26 RW normal 2304 0 3086848 4194304 ------------------------------------------------------------------------------------ 9 total 9088 0 11339136 19994880 AX3PAR01 cli% and also the view of the CPG space in the GUI is being displayed correctly again, see attachment. HP asked to upgrade to 3.1.3 (MU3) as soon as it's available. These problems should be fixed automatically then. Regards.
