https://community.hpe.com/t5/proliant-deployment-and/hsz-disk-error/m-p/3343128#M941 I can not say for sure why your getting this error, but it could be related to a bus reset.<BR /><BR />If you want, I can review some SAN documentation that you would have to put together. Things like your switch configuration and your hsg80 config. <BR /><BR />HSZDisk is one of the intermediate drivers that Compaq uses on Windows 2000 to present SAN based storage to the host. If you lose access to a disk for some reason, an HSZ error will occur. If you see this on multiple servers at arond the same instance, it could mean that aside from the disk error, you probably have some SAN switch zoning issues.<BR /><BR />Steven Thu, 29 Jul 2004 23:56:27 GMT Steven Clementi 2004-07-29T23:56:27Z https://community.hpe.com/t5/proliant-deployment-and/hsz-disk-error/m-p/3343127#M940 Hi<BR />We are running a HSG SAN environment.<BR /><BR />On one of our Windows 2000 Servers I am continually getting the following error in the Application Log<BR />The full data field is giving me the following info.<BR /><BR />Source HS_Service<BR />Event Id 1<BR />Description HSZDisk error detected<BR /><BR />0000: fd ff ff ff a8 00 00 00 ýÿÿÿ¨...<BR />0008: 48 01 00 00 02 00 01 00 H.......<BR />0010: 03 00 00 00 04 00 00 00 ........<BR />0018: 03 00 00 00 00 00 00 00 ........<BR />0020: 00 00 00 00 00 00 00 00 ........<BR />0028: 05 00 00 00 41 00 18 00 ....A...<BR />0030: 32 30 30 34 30 37 32 38 20040728<BR />0038: 31 31 35 36 35 34 2c 31 115654,1<BR />0040: 35 2d 30 30 30 30 00 00 5-0000..<BR />0048: 81 00 29 00 57 69 6e 64  .).Wind<BR />0050: 6f 77 73 20 4e 54 20 35 ows NT 5<BR />0058: 2e 30 20 62 75 69 6c 64 .0 build<BR />0060: 20 32 31 39 35 20 53 65 2195 Se<BR />0068: 72 76 69 63 65 20 50 61 rvice Pa<BR />0070: 63 6b 20 34 00 00 00 00 ck 4....<BR />0078: 21 01 0b 00 4b 42 43 49 !...KBCI<BR />0080: 50 53 51 4c 30 31 00 00 PSQL01..<BR />0088: 21 04 10 00 30 00 30 00 !...0.0.<BR />0090: 31 00 46 00 45 00 31 00 1.F.E.1.<BR />0098: 30 00 30 00 41 04 05 00 0.0.A...<BR />00a0: 31 00 43 00 00 00 00 00 1.C.....<BR />00a8: f0 00 06 00 a4 6d d5 98 ð...¤mà  <BR />00b0: 00 00 00 00 03 00 00 80 ....... <BR />00b8: 00 13 00 00 01 00 03 00 ........<BR />00c0: 00 00 05 0e 00 00 00 00 ........<BR />00c8: 0a 45 28 03 51 20 00 2a .E(.Q .*<BR />00d0: 80 00 00 00 00 00 00 00  .......<BR />00d8: 00 00 00 00 00 00 20 20 ...... <BR />00e0: 20 20 20 20 5a 47 30 34 ZG04<BR />00e8: 36 30 36 38 31 31 56 38 606811V8<BR />00f0: 37 50 00 00 00 00 00 42 7P.....B<BR />00f8: 30 31 34 42 46 30 33 36 014BF036<BR />0100: 36 35 32 32 33 20 20 20 65223 <BR />0108: 20 20 20 00 00 00 00 00 .....<BR />0110: f0 00 01 00 a4 6d d5 28 ð...¤mà (<BR />0118: 00 00 00 00 03 00 00 80 ....... <BR />0120: 00 13 00 00 00 00 00 00 ........<BR />0128: 00 00 00 00 00 00 00 00 ........<BR />0130: 00 00 00 00 00 00 00 00 ........<BR />0138: 00 00 00 00 00 00 00 00 ........<BR />0140: 00 00 00 00 00 00 00 00 ........<BR /><BR />If anyone can help me out with this I would rea Wed, 28 Jul 2004 06:11:15 GMT https://community.hpe.com/t5/proliant-deployment-and/hsz-disk-error/m-p/3343127#M940 Brendan Lynch 2004-07-28T06:11:15Z https://community.hpe.com/t5/proliant-deployment-and/hsz-disk-error/m-p/3343128#M941 I can not say for sure why your getting this error, but it could be related to a bus reset.<BR /><BR />If you want, I can review some SAN documentation that you would have to put together.
